Obviously, the larger problem on our highways is speeding truckers. But truck accident lawyers should keep in mind that there can be a negligence component to driving too slow. Most states have laws that require trucks to travel fast enough so that they don’t impede or block the normal and reasonable flow of traffic. Because of the nature of the cargo and/or the truck driver’s lack of comfort/qualifications to drive the truck, some trucks drive at unsafely low speeds. Many truck accidents and car accidents are caused by a speed differential.
