What should you do if the road becomes very slippery due to glare ice?

Accelerate gently to regain control.
Stop driving as soon as you can safely do so.
Change lanes to find better traction.
Increase your speed to avoid skidding.

The correct answer is: Stop driving as soon as you can safely do so.

When dealing with very slippery conditions caused by glare ice, stopping driving as soon as it is safe to do so is the most appropriate action. Glare ice significantly reduces traction, making it difficult to control the vehicle and increasing the likelihood of skidding or losing control. By safely stopping, you minimize the risk of an accident and allow conditions to improve, if possible. This approach is particularly important because attempting to accelerate gently could lead to losing control since the tires would struggle to grip the road. Changing lanes in search of better traction might not be effective; in many cases, ice is pervasive, and moving to another lane could expose you to similar or worse conditions. Lastly, increasing speed is counterproductive on ice, as higher speeds can exacerbate skidding and make it nearly impossible to regain control. Therefore, the best course of action in such a scenario is to prioritize safety by halting your vehicle when conditions become hazardous.
