When driving on black ice, what is a prudent action to take?

Steering gently and avoiding sudden movements when driving on black ice is essential for maintaining control of the vehicle. Black ice creates a layer of transparent ice on the road that significantly reduces traction, making it easy for a driver to lose control if they make abrupt steering, braking, or acceleration movements. By steering gently, the driver can better navigate the slick surface without causing the wheels to slide or skid. This approach allows for smoother driving and helps maintain stability, essential for safely maneuvering on icy roads.

Other options, such as accelerating to maintain speed or using high-beam headlights, could lead to a loss of control or decreased visibility, which can exacerbate the risks associated with black ice. Switching off the engine does not address the need for careful control while driving. Thus, the strategy of gentle steering is the most effective way to handle the conditions presented by black ice.
