What technique is commonly recommended for safe driving on slippery surfaces?

Maintaining a tight grip on the wheel is critical for safe driving on slippery surfaces. This technique allows the driver to maintain better control of the vehicle, particularly when navigating through conditions that can cause loss of traction, such as rain, ice, or snow. A firm grip enables quick responses to any changes in the vehicle’s direction, helping to prevent situations where the vehicle may skid or slide out of control. By keeping the steering steady and responsive, a driver can better manage the vehicle's trajectory and maneuver effectively to avoid hazards.

The other techniques mentioned do not address the immediate challenges of driving on slippery surfaces as effectively. For instance, accelerating slowly is important to avoid spinning wheels, but does not directly enhance control when skidding occurs. Using cruise control is inadvisable on slippery surfaces as it can reduce the driver's ability to react swiftly to changing conditions. Braking hard if skidding occurs can actually exacerbate the situation and lead to a complete loss of control. Therefore, maintaining a tight grip allows for the most effective management of the vehicle in slippery conditions.
