The USA relies on the Motorcycle Safety Foundation (MSF) Basic RiderCourse — typically a single weekend. There is no mandatory graduated licensing system at the federal level. Riders can legally operate any engine size after passing one short course, with no minimum period on a restricted licence. This contrasts sharply with the EU/UK tiered A1/A2/A system, which restricts new riders to lower-power machines for at least two years. The result: US motorcyclists are disproportionately represented in fatality statistics, with a VMT death rate of 25.8 per billion VMT — roughly 19× the car rate.

Much of the US road network was designed around the car, with wide lanes, long sight lines, and high posted speeds. Rural interstates and state highways often carry 70–80 mph limits. Research consistently links higher speed limits to higher fatality severity. The US also has a higher proportion of rural road deaths than comparable nations — rural roads account for roughly 46% of US traffic fatalities despite carrying far less traffic.

The US pedestrian death rate (7,522 in 2022) is exceptionally high for a wealthy nation. Many suburban and exurban areas lack footpaths, crossings, or street lighting. Wide multi-lane arterials with high speed limits are hostile to pedestrians. The rise of large SUVs and pickup trucks — which have higher hood heights and reduced forward visibility — has been linked to a sharp increase in pedestrian fatalities since 2010.

The US legal BAC limit is 0.08% — higher than the 0.05% limit in most of Europe and Australia. Alcohol is involved in roughly 30% of US traffic fatalities. Enforcement is inconsistent across states, and sobriety checkpoints are prohibited in some jurisdictions on constitutional grounds. The lack of widespread public transport in most US cities also means driving after drinking is more common than in countries with strong transit networks.

Seat belt use in the US averages around 91% nationally, but varies significantly by state. Only 34 states have primary enforcement laws (allowing police to stop a driver solely for not wearing a belt). Motorcycle helmet laws are similarly fragmented: only 18 states require all riders to wear helmets. States without universal helmet laws consistently show higher motorcyclist fatality rates.

Survival after a serious crash depends heavily on the speed and quality of trauma care. The US has world-class trauma centres, but uneven geographic coverage — particularly in rural areas — means that time-to-care can be significantly longer than in countries with universal healthcare systems. Uninsured crash victims may also delay or avoid seeking treatment, affecting injury outcome statistics.
