Before you get on the road with your car rental in Montgomery, there are a few traffic laws you should know about. For example, driving is strictly on the right side of the road, and a speed limit of 70 mph (113km/h) is to be observed on the Interstate, 65 mph (104km/h) for roadways with four or more lanes and 55 mph (88km/h) on other roadways unless marked otherwise. In addition to that, you can’t drive while under the influence of alcohol (0.08% is the maximum legal limit), and all passengers inside the rental car in Montgomery should have their seatbelts fitted regardless of where they are sitting. You can always confer with the Alabama DMV for the latest changes in traffic rules.
