What should you do if your vehicle breaks down on the freeway?

Answer: B — Stay in your vehicle with your seatbelt on

When your vehicle breaks down on the freeway, it is crucial to prioritize safety. Staying in your vehicle with your seatbelt on is the most effective way to protect yourself. Freeways often have high-speed traffic, and stepping out of your car can put you at significant risk of injury from passing vehicles. By remaining in the vehicle, you are safer while waiting for assistance. You should turn on your hazard lights to alert other drivers that your car is not operational. If you need to call for help, it's advisable to do so from inside the vehicle, as this reduces the risk of an accident. Other options, such as leaving your vehicle, attempting immediate repairs, or using a phone while driving, pose various safety risks that could endanger your life and others on the road.
