its the law over here to wear a seat belt. i always wear mine, its the first thing i do when i get in a vehicle, due to a bad crash i had a few years back with my dad driving.
if you are stopped by the feds and you havent got your belt on, youv got a fine.
if you and your buddy are in the car and your buddy doesnt have his belt on, the driver gets a fine.
if you have a full car load and one person out of 5 doesnt have there belt on, the driver gets a fine.
its the same for all vehicles. im not to sure what the amount of the fine you get is but its more than enough.
safety laws over here are tight for road users over here. even though you have air bags etc in your vehicle, you MUST wear your belt.
