If the drive wheels have poor traction, retarders may cause _______.

Explanation:
Retarders slow a vehicle by creating resistance in the drivetrain, which the drive wheels must transmit to the road. When the drive wheels don’t have good traction, the tires can’t grip the road to convert that resistance into effective braking. Instead, the wheels may start to slip across the slick surface, causing the vehicle to skid. The other effects aren’t the typical result in this situation: overheating isn’t an automatic outcome of using a retarder on poor traction, braking force isn’t increased because grip is lacking, and squealing is more about friction noise from locked brakes or tires rather than the slipping skid described here.
