Maryland Ranks #3 Nationwide as Auto Registrations Rise 5.53%, Adding 103,396 Vehicles

Maryland has emerged as a national leader in vehicle registration growth, adding more automobiles than any other state in America between 2019 and 2023. The Old Line State’s 103,396-vehicle gain outpaces even larger states like Texas and California, which saw their registrations plummet. With a 5.53% growth rate, Maryland ranks third nationally, a remarkable performance in a region where every neighboring state experienced significant declines.

The analysis, conducted by RoadRunner Auto Transport, examined USDOT Motor Vehicle Registration data (MV-1 series) across all 50 states. Maryland’s performance is especially striking given the Northeast region’s average decline of -18.47%, the steepest of any U.S. region.

Maryland’s Vehicle Growth: By the Numbers

Maryland’s automobile growth outpaced the national average by over 16 percentage points. While the average U.S. state saw an 11% decline in auto registrations, Maryland moved decisively in the opposite direction. The state’s truck registrations showed even stronger growth at 29.44%, adding 647,305 trucks to Maryland roads over four years.

Maryland’s Auto Registration Growth by Year

Maryland’s growth story is defined by one extraordinary year: 2020-2021, when the state added 252,840 automobiles, a 13.87% single-year surge. This massive gain more than offset declines in other years, leaving Maryland with a net positive of over 103,000 vehicles. The 2021 spike likely reflects a combination of pent-up pandemic demand and Maryland’s strong economic recovery.

Maryland vs. Neighboring States (2019-2023)

Maryland stands alone in its region as the only state with positive growth. Delaware recorded the nation’s steepest decline at 63.47%, losing nearly two-thirds. Virginia, despite its economic strength, shed 273,130 vehicles. Pennsylvania lost nearly 665,000 autos, and West Virginia dropped 21.37%. Maryland’s growth amid this regional contraction is exceptional.

States Adding the Most Vehicles (2019-2023)

When measured by raw vehicle count, Maryland leads the nation. The state added 103,396 automobiles, nearly 20,000 more than second-place Tennessee and almost double Montana’s gain. This reflects Maryland’s larger vehicle base: while Montana achieved the highest percentage growth (12.76%), Maryland’s 5.53% rate applied to a larger fleet produced the biggest absolute increase.

The Only 8 States With Positive Growth (2019-2023)

Maryland joins an exclusive club of just eight states that grew their auto registrations while 42 states declined. Notably, Maryland is the only Northeastern state in this group, and the only one from the region that posted positive growth of any kind. The other seven states are concentrated in the South, Mountain West, and New England.

Northeast Region Performance

The Northeast suffered the steepest regional decline in the nation at -18.47% on average. Maryland and Maine are the only states in the region to post positive growth. New York lost over 1.6 million vehicles (36.40%), and Delaware’s 63.47% plunge represents the worst performance of any state nationwide. Maryland’s positive growth in this environment is a dramatic outlier.

Maryland’s Vehicle Fleet Composition (2023)

Trucks now comprise nearly 58% of Maryland’s vehicle fleet, with a striking 29.44% growth rate that added 647,305 trucks since 2019. This truck surge, reflecting national preferences for SUVs and pickups, drove much of Maryland’s overall fleet expansion. Motorcycles and buses both declined, suggesting shifting commuter patterns and transportation preferences in the post-pandemic period.

National Context: Where Maryland Fits

Methodology

Study Overview

RoadRunner Auto Transport analyzed official motor vehicle registration data from the U.S. Department of Transportation to identify which states experienced the fastest and slowest growth in registered vehicles between 2019 and 2023.

Data Collection Process

• Primary Data Source: USDOT Open Data Portal – Motor Vehicle Registrations, 1900-2023 (MV-1, wide format). This dataset is compiled from the Federal Highway Administration’s annual MV-1 series, which aggregates state-reported vehicle registration figures.
• Geographic Scope: All 50 U.S. states
• Time Period: 2019-2023 (selected to avoid over-weighting 2020 pandemic-year anomalies in year-over-year calculations)

Calculation Methodology

• Absolute Growth: Calculated as Registrations_2023 minus Registrations_2019 for each state.
• Percent Growth: Calculated as ((Registrations_2023 / Registrations_2019) – 1) x 100.
• Ranking: States were ranked by percent growth (primary metric), with secondary analysis by absolute growth for large-state context.

Quality Assurance

All 50 states were verified to have complete registration data for both 2019 and 2023. Outliers were flagged and cross-referenced against source data to ensure accuracy. Regional classifications follow U.S. Census Bureau definitions.
