Before you get on the road with cheap car rentals in Las Vegas, here are the driving rules you need to know. Taking calls, texting, accessing the internet, and using your phone is illegal when driving in Las Vegas unless you use a hands-free kit. You are supposed to give way to pedestrians, even when they are crossing in undesignated areas. You are supposed to stop and give way to school buses with flashing lights and an extended stop sign. If you encounter an emergency vehicle with flashing lights, drive cautiously, and if possible, go to the lane not adjacent to the one where the emergency vehicle is stopped. You can turn right on a red light, but only after coming to a full stop, unless there's a sign prohibiting right turns.
