Driving in the United States Risk Calculator

Driving is common in the U.S., but it carries real risks of fatality and serious injury. This calculator estimates your risk for a chosen distance and conditions.

Your Inputs

Choose your driving conditions below:

Select your distance (this sets how much exposure you have):

Driving at night increases risk because more crashes happen in fewer miles:

Wearing a seat belt greatly reduces the risk of death or serious injury:

Your Results

Your estimated chance of being in a fatal crash is {{One_in_X:{result}}}.

Your estimated chance of being injured in a crash is {{One_in_X:{result}}}.

Calculation note: Each model first computes the expected number of events λ from the verbatim base rates (per 100 million vehicle miles traveled), scaled by distance and modifiers. It then converts λ into a probability of at least one event using the Poisson formula \(p = 1 - e^{-λ}\). Because <RiskModel> only supports numeric constants and math operators, the constant *e* is approximated as 2.718281828 and exponentiation is written with the `^` operator.
