It depends on the laws in your state. Each state varies on the laws for carseat and booster laws.

Really, yes. It's because seat belts are designed to fit adults over 5ft tall, and children that are under 4ft 9in tall really don't fit them. It's not about how old they are, it's about safety for their size. Here's a 5-step test to see if they pass, and if the child does, then he/she would be fine in just a seat belt, if not then a booster would be needed.

  1. Does the child sit all the way back against the auto seat?
  2. Do the child's knees bend comfortably at the edge of the auto seat?
  3. Is the lap belt touching the top of the thighs, not the tummy?
  4. Is the shoulder belt centered on the shoulder and chest?
  5. Can the child sit like this the whole trip?

It's really different depending on where you live. Here in Canada the laws were just changes so that if a child meets one of the following 3 criteria they don't need a booster seat. 1. the child is 8 years or older, 2. the child weighs 36kg (80lbs) or 3. the child is 145cm (4 feet 9 inches tall). I totally agree with the above answer that it shouldn't be an age thing because you could have an 8 year old that is only 4 feet tall and weighs only 70 pounds.

What age do you have to be to seat in the front of a car in NJ?

It's not about how tall you are, this is from the NY State Ploice website. New York's Occupant Restraint laws require the following: Children up to the age of 4 must be properly restrained in a federally approved child safety seat that is attached to a vehicle by a seat belt or universal child restraint anchorage (LATCH) system. Children less than age 4 but weighing more than 40 pounds may be restrained in a booster seat with a lap/shoulder safety belt. Children ages 4, 5, 6 and 7 must be properly secured in an appropriate child restraint system, one for which the child meets the height and weight recommendations of the child restraint manufacturer.* An appropriate child restraint system is one that meets the child's size and weight recommended by the manufacturer. A vehicle's safety belt is NOT a child restraint system. Children riding in booster seats must be secured with a combination lap/shoulder seat belt, NEVER secure a child in a booster seat with only a lap belt. From the age of 8 until they reach their 16th birthday, children must be restrained in a seat belt when they ride in the back seat. Front seat passengers must be properly restrained at all times, regardless of age. Children 12 years and younger should ride in the back seat. By simply buckling up your child in the back seat reduces his/her risk of death by 33%. *It is recommended that booster seats be used until your child is 4 foot 9 inches tall or weighs 100 pounds.
