Oregon state law requires that all children must ride in a federally approved car seat until they weigh at least 40 pounds. Infants must ride in rear-facing car seats until they reach both one year of age AND 20 pounds.
Effective July 1, 2007, a new Oregon law further requires that children use a booster seat until they are 4'9" tall, unless they are at least 8 years old. Oregon strongly recommends that children under age 12 ride in the back seat. All Oregon passengers and drivers are required to wear a seat belt.
