Given that semi-trucks haul heavy and long trailers, accidents involving them can sometimes cause heavy traffic snarl-ups. For this reason, law enforcement usually looks for a quick solution, which may entail calling a roadside towing and recovery company at your expense. If you are operating a fleet of semis, you are better off if you already have an agreement with a towing company. If not, you can still make an arrangement as soon as you possibly can. You may want to consider Pro-Tow for such services.
