What should you do when driving on "black ice"?

Accelerate to gain traction
Brake gently and steer straight
Turn sharply to maintain control
Increase speed to pass quickly

The correct answer is: Brake gently and steer straight

When driving on "black ice," maintaining control of the vehicle is crucial due to the slippery and hazardous conditions. Braking gently and steering straight minimizes the risk of losing traction. This technique allows for a more gradual reduction in speed without causing the wheels to lock up or the vehicle to skids. Gently braking lets you assess the level of traction without overwhelming the tires, and steering straight helps avoid sharp movements that could lead to a loss of control. Such actions are especially important on black ice, where sudden maneuvers can result in skidding or even spinning out. Other reckless options, such as accelerating, turning sharply, or increasing speed, can exacerbate the risk of losing control on the ice. These methods can lead to a dangerous situation, making the importance of gentle braking and maintaining a straight path vital for safety on slippery surfaces.
