If you've been using scales to determine whether junior needs a car seat anymore, toss the strategy. As of Sunday, all children in Colorado under the age of eight---regardless of weight---will be required to use a car or booster seat. If an officer suspects a child under eight is riding without a proper seat, the driver can be pulled over, writes the Colorado Springs Gazette. Prior law required children under six to be in a seat. "We are looking for a child that’s at least eight years old and at least 55 inches tall---that is the guidance for getting out of the booster seat," local police sergeant Steve Noblitt tells Fox 21 in Colorado Springs.
