Thank you, Ian. Impressive execution by both of our groups contributed to a record-setting quarter on many metrics. Within our Environmental Solutions Group, an improving supply chain supported higher production levels and with increased sales volumes, contributions from recent acquisitions, robust aftermarket demand and strong price realization, we were able to deliver a 22% year-over-year net sales increase and a 220 basis point improvement in adjusted EBITDA margin. During Q2, we were again able to increase production levels at our largest manufacturing facility achieving the third successive quarter of production growth as the overall supply chain environment continues to improve. This strong execution contributed to a 35% year-over-year increase in [Technical Difficulty]. And what is typically a seasonally strong quarter, our aftermarket revenues were also up 18% over last year, with particular strength in parts sales. In addition to strong organic growth, our recent acquisitions also contributed with Trackless, our most recent acquisition completed early in the quarter off to a strong start. Collectively, the acquisitions added approximately $22 million to our top line during the quarter. While we are encouraged by the improving supply chain environment, we are still not out of the woods and there continue to be pockets of supply-related disruptions for certain components, like hydraulics and pumps. Given that, we are not yet maximizing our production capacity and continue to experience some inefficiencies. Chassis availability also continues to be a constraining factor within our dump body businesses, particularly for our businesses that build on Class 5 chassis. Our Safety and Security Systems Group again delivered impressive results during the quarter, with record net sales and adjusted EBITDA. SSG's second quarter results included 15% top-line growth and an adjusted EBITDA margin of 21.9%, a 300 basis point improvement compared to last year and above its target range, which we increased earlier this year. Over the last few years, we have made several investments in organic growth within SSG, including purchasing the University Park facility and in sourcing production of several key components. These investments include the addition of a third printed circuit board line to increase production volumes of public safety equipment, achieve cost savings and reduce reliance on suppliers. The new production line is expected to be operational in the third quarter. We expect that the broad actions we have taken to mitigate component shortages, including investments to in-source production and bring additional suppliers online will provide meaningful long-term benefits to Federal Signal. Other highlights of the quarter include the publication of our latest sustainability report, demonstrating our ongoing commitment to environmental, social and governance initiatives. The report highlights the progress we've made against our sustainability goals that were established in 2018, including achieving our targeted 10% reduction in water and electricity intensity early. In the report, we highlight the ways in which we make a difference to our customers, our communities and our environment. We know that it is a global manufacturer of critical infrastructure and safety products. We have the responsibility to do the right thing, operate sustainably and with a long-term fact based view on issues regarding the environment society and corporate governance and positively impact our employees, customers, partners and stakeholders at large. These efforts also position us well in the communities in which we operate and serve as a differentiating factor in our ability to attract labor at most of our facilities. Demand for our products and our aftermarket offerings remains at unprecedented levels with both our orders and backlog this quarter again setting new company records. As we talked about previously, there are several macroeconomic tailwinds contributing to the strong demand we are currently experiencing within our municipal markets, we are continuing to see the benefits from the American Rescue Plan, which in 2021 earmarked $350 billion for state, local and territorial governments for a variety of purposes, including the maintenance of essential infrastructure such as sewer systems and streets. In the second quarter, municipal orders were up 13%, compared to last year, primarily driven by significant increase in demand for sewer cleaners. As a reminder, approximately 75% of our sewer cleaners orders include a hydro-excavation, our safe-digging package, allowing the unit to be utilized in a variety of applications. We also continue to expect meaningful multi-year tailwinds arising from the $1.2 trillion Infrastructure Act, which has $550 billion earmarked for new investments in roads, bridges, power, water and broadband infrastructure, public transportation and airports. Today, nearly 35,000 projects have been awarded funding from the Bipartisan Infrastructure Law. They range from repaving roads and water system upgrades funded through formula grants to state to competitive funding for massive bridge and transit projects. Our teams are working with our customers in the designated area as they evaluate their equipment needs to support these large multiyear-scale projects. With the funding available to support broadband infrastructure development, we have seen additional interest in our broad range of safe-digging product offerings that can vacuum excavate and/or convey materials in a safe and efficient manner. With that orders, our safe digging trucks were up 20%, compared to the prior year. As another example of the potential application for the use of our safe-digging products, there is a significant operating in California to mitigate the risk associated with wildfires with major utility companies recently announcing that it is seeking $8 billion in funding to barry power lines underground. We are also continuing to see benefits from the infrastructure bill within SSG. In particular with higher demand for warning systems, the Infrastructure Act earmarked $6.8 billion for the Federal Emergency Management Agency or FEMA to invest in disaster mitigation programs. This includes $500 million over five years to provide hazard mitigation assistance to local governments through the STORM Act. To date, we have received over $4 million in warning system orders supported by FEMA funding and are currently working with several counties that have been awarded grants totaling several million dollars to expand their tornado warning system. We have received multiple proposals from communities across the country that are seeking government grants from this funding source to update or expand warning system. As part of our warning system offerings, we also provide ongoing maintenance and subscription, alerting services which following the initial sale of the warning equipment provide for our long-term recurring revenue stream. SSG has recently introduced a couple of new features key to advancing the safety and security of communities and workplaces. The first is lightning detection alerting which are additions to our flagship commander one outdoor warning siren activation and monitoring system. This feature is ideal tool or industrial chemical plants, outdoor recreational areas, parks and campuses, where lightning is a threat to employees and communities. The second is a new option for siren communication with our IoT family of products. These devices allow for quick upgrades from legacy radio technologies to secure cellular communication. With higher frequencies of natural disasters such as wildfires, hurricanes, tornadoes and floods, we are proud that our products play a role in helping to keep communities safe. During the second quarter, the U.S. Department of Energy also released a notice of intent to invest $2 billion from the Inflation Reduction Act to accelerate domestic manufacturing of electrified vehicle. These investments are expected to be made available in the coming months. Electrification remains a key area of investment for the company and we expect this public funding source to support future growth related both to our EV product lines, as well as our platform of specialty vehicles that support metal extraction. During the second quarter, despite increased production levels that contributed to record quarterly sales, our orders once again exceeded shipments. In fact, the second quarter represented the 10th successive quarter that our orders have outpaced sales. With this unprecedented demand contributed to record backlogs, lead times for certain products have become extended. And consequently, we may see some lumpiness in ESG order trends as we move forward, which may impact comparability from quarter to quarter. In addition, while orders within SSG in the front half of the year were outstanding, including benefits from certain large fleet orders, we may see some moderation in SSG orders in the second-half of the year with forward scheduling a police vehicle model year changeover in Q4. We remain focused on increasing production levels to build more trucks as we aim to reduce current backlog and lead times, while continuing to maintain healthy order intake. I now want to take a few minutes to provide an update on a couple of our organic growth initiatives. Our focus on 80-20 improvement is deeply ingrained in our culture and has played and will continue to play a key role in driving our organic growth and industry-leading margins. As discussed on the last earnings call, we hired a dedicated resource tasked with driving additional throughput projects across many of our businesses as we seek to reduce current lead time at several of our businesses. This resource has already conducted a series of 80-20 and lean manufacturing session at our Elgin Street Sweeper facility, lean initiatives have initially focused on synchronizing fabrication and paint processes within assembly demand. This improved flow is expected to increase throughput by eliminating double handling of materials, maximizing paint line capacity and assembly productivity. At our Travis party and trailer facility, the management team initiated a product line simplification initiative. Similar to the successful Ox Bodies dump by the SKU reduction that we talked about in our last earnings call. The Travis team identified over 9,500 current combinations of trailer offerings and the first round of its 80-20 analysis achieved a 30% reduction in variations with continued standardization underway. Moving on to aftermarkets which represented approximately 28% of ESG's revenues during the quarter, mainly due to the strength and parts sales that I noted earlier. Aftermarket remains a key strategic initiative of ours, and we see additional opportunities to grow that business by expanding into new geographies. In addition, we made meaningful investments in the first-half of '23 to replenish our rental fleet and support the anticipated continuation of high demand for rentals and used equipment. We also continue to invest in new product development and I wanted to touch on a few recent product innovations. During the second quarter, SSG introduced the high literal lead, a new design of our popular mini light bar with improved optical performance and a sleeker more attractive appearance. The wide variety of mounting options, colors and flash patterns ensure there is a suitable model for on-road or off-road utility telling in construction vehicles. In addition, reduced availability of Class 3 to Class 5 chassis continues to be a constraint for our dump body business. As a result, our teams have launched products that utilize chassis that currently have more availability. As an example, we recently introduced an aluminum dump body product offering designed for the widely available Ford at 350 pickup chassis that has been well received in the market. On the M&A front, we were pleased to announce the closing of the Trackless acquisition in April, and are encouraged with its financial performance in the quarter. Trackless is a leading Canadian manufacturer of multipurpose off-road municipal tractors, and a variety of attachments we'd provide year-round value to its customers. The Trackless integration is well underway, and we are excited about the opportunities to leverage our existing distribution channel in the US to expand the geographic reach of Trackless products and accelerate the growth trajectory of this business. Our continued growth through disciplined M&A differentiates Federal Signal as an accumulator of leading brands of specialty vehicles and supporting aftermarket offerings. Our deal pipeline remains very active and we continue to expect M&A to be an important part of our future. Turning now to our outlook for the rest of the year, demand for our products and our aftermarket offerings remains at unprecedented levels with both our orders and backlog this quarter, again setting new company records. With our second-quarter performance, our record backlog and improving supply chain conditions, we are raising our full-year adjusted EPS outlook to a new range of $2.30 to $2.46 from the prior range of $2.21 to $2.43. We are also increasing the low end of our full-year net sales outlook range by $30 million, establishing a new range of $1.65 billion to $1.72 billion. At this time, I think we're ready for questions. Operator?
