how old do you have to be to sit in the front

In Australia, the rules for front-seat passengers are as thrilling as watching paint dry but just as important. Generally, children under the age of 4 years should never sit in the front due to airbag risks. From 4 to 7 years, they can sit in the front only if suitable child restraints are used and no rear seats are available. Once they hit 7 years, they can sit up front with a regular seatbelt, but the rear seat is always the safer bet. Local laws can vary a bit, so it's worth double-checking with your state's road authority or ServiceCentral.
