Cannabis Impaired Driving Laws

Cannabis impaired driving laws vary by state, but all aim to ensure road safety. Key regulations include standardized field sobriety tests and blood tests to measure THC levels.

Standardized Field Sobriety Tests

Law enforcement uses standardized field sobriety tests to assess a driver's impairment. These tests include walking a straight line, standing on one foot, and following a pen with eyes.

Blood Tests for THC Levels

Blood tests are used to measure THC levels in a driver's system. Most states have a legal limit of 5 ng/mL or less for drivers.

Penalties for Impaired Driving

Penalties for cannabis impaired driving include fines, license suspension, and imprisonment. Repeat offenders face harsher penalties.

State-Specific Laws

State laws vary regarding the definition of impaired driving and the specific penalties. For example, Colorado and Washington have specific THC-impaired driving laws.
