Notes
- Failure of the driver, a front-seat passenger or a child under 18 to wear a seat belt is a primary offence; unbuckled back-seat occupants aged 18 and over may be issued a summons only if the vehicle is stopped for another reason.
- The Division of Highway Traffic Safety guide words the youngest-child rule as 'under the age of 2 years and 30 pounds'; the driver manual says 'under age two and those who weigh less than 30 pounds'.
