New York State highway use tax (TMT)

New York State Highway Use Tax (TMT) is imposed on motor carriers operating certain motor vehicles on New York State public highways (excluding toll-paid portions of the New York State Thruway). The tax is based on mileage traveled on New York State public highways and is computed at a rate determined by the weight of the motor vehicle and the method that you choose to report the tax.

Motor carrier safety enforcement (PRISM)

PRISM is a federal and state partnership developed to reduce commercial motor vehicle accidents. PRISM identifies motor carriers with poor safety records and holds the carriers responsible for the safety of their operations.

PRISM links the motor carrier safety information of the Federal Motor Carrier Safety Administration (FMCSA) with state motor vehicle registration processes to determine the safety and fitness of motor carriers.
