Which condition is required when towing a trailer on a highway?
Correct answer: B. – The trailer must be attached and equipped to follow without snaking
North Carolina law requires a trailer or other towed vehicle to be firmly attached and equipped so that it does not snake but follows the towing vehicle’s path. When the primary attachment is a ball hitch, safety chains or cables strong enough to hold the trailer’s gross weight are generally required if the primary connection fails.
