When driving next to a large vehicle in a high wind, what should you do?

Turn on your headlights
Increase your speed
Maintain a steady speed
Tailgate

The correct answer is: Maintain a steady speed

When driving next to a large vehicle in a high wind, it is important to maintain a steady speed. This is because large vehicles, such as trucks or buses, can create a wind tunnel effect which can cause your vehicle to sway and potentially lose control if you're traveling at varying speeds. Turning on your headlights or increasing your speed can actually be dangerous as it may create more wind resistance and make it harder to maintain control of your vehicle. Tailgating, or following too closely behind the vehicle, is also dangerous as it limits your ability to react to any sudden movements of the larger vehicle. Therefore, maintaining a steady speed is the best and safest option in this situation.
