Ramps must be cleared of snow and ice before towing operations; which substance must be removed to ensure safety?

• A. Dirt
• B. Sand
• C. Snow and ice
• D. Water

Answer: (C)

The key idea is surface condition and traction. When a ramp has slippery material, the friction between tires and the ramp drops, making it easy for wheels to slide, for the tow vehicle to lose steering control, or for the tow gear to slip during hookup and movement. Clearing the ramp of snow and ice restores a dry, grippy surface, giving the tires proper traction and allowing brakes, steering, and towing hardware to function safely. Dirt or water can present issues, but snow and ice create the most hazardous, traction-sapping conditions for towing operations, and the procedure called for is to remove them.
