When driving into a headwind, what may be necessary?

When driving into a headwind, it may be necessary to accelerate to maintain your speed and control of the vehicle. Headwinds can create significant resistance, making it harder for your vehicle to move forward at the same speed. By accelerating, you can counteract this resistance and ensure that you do not lose momentum, which is particularly important for safety and handling. This increase in speed can also help keep your vehicle stable, especially when going uphill or when navigating windy conditions.

In contrast, suddenly braking or turning on hazard lights would not address the challenge posed by the headwind and may create more problems than they solve. Lowering your speed may also lead to difficulties maintaining control and could increase the strain on the vehicle's engine, making it less efficient in this adverse condition.
