It depends on what state your in but I believe that the no seatbelt law is nationwide in which case you will get a ticket if in the front seat of a car and are not wearing a seatbealt if your over the age set by the law. In the UK it is always an offence.
"There is no age restriction for sitting in the front seat in BC traffic law."
I found a really helpful PDF put out by the Utah Safety council. According to it, there is no law regarding children riding in the front seat of the car: http://www.utahsafetycouncil.org/assets/pdf/utboosterlaw.pdf It is recommended that children under age 12 ride in the back seat, or to turn the airbags off if a child under 12 is in the front seat, but there is no law saying you have to.
First of all, people riding in the front, as well as the back seat are required to wear seat belts. It's against the law in most states for a child to sit in the front seat of a car that has front air bags. Only children taller than 4'9' in height, and/or the age of twelve should ride in the front seat of a vehicle.
You may not ride in the front seat of a car till you are 13 or older and must be over 85 pounds but this does not apply to cars without a back seat.
Children must be at least 13 years old to ride in the front seat of a car in Massachusetts, according to state law. This measure is in place to ensure their safety in case of an airbag deployment.
Depends on how old your child is, his or her weight and how tall he or she is and the country in which you are driving.
I believe CA state law requires it in the back seat. Call the CHP office near you to ask this question before you get a ticket.
depends on the car seat type and other stuff
60 pounds
Four years old. However, studies show that there is significant risk of injury or death for those under 14 from front seat airbags.
In the US, under current law, this is probably illegal in every state, though I'm not positive about that. The usual cutoff age for riding in the front seat is 12.
