What is the speed limit for a tow truck?
2 Answers
When towing a disabled vehicle on the highway, the speed of the tow truck must not exceed 60 kilometers per hour as per regulations. It should drive in the far-right slow lane with hazard lights activated. Below is an introduction to tow trucks: 1. Overview: The tow truck is a vehicle originally produced in West Germany, developed from the Iveco Magirus off-road vehicle and manufactured by the defense vehicle division of Iveco Magirus. 2. Function: Tow trucks are powered by electric motors and utilize their towing capacity (2.0 to 8.0 tons) to pull several cargo-loaded carts. They are commonly used for transporting large quantities of goods within or between workshops, such as moving parts from warehouses to assembly lines in automobile manufacturing or handling luggage at airports. 3. Principle: The traction control system's control unit is a computer that monitors the speed of all four wheels and the steering wheel's turning angle. During acceleration, if the computer detects an excessive speed difference between the driving and non-driving wheels, it immediately determines that the driving force is too high and sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the driving wheels.
I've been driving semi-trailers for over a decade, and the maximum speed is never fixed. On regular highways, around 90 km/h is the most stable, while on winding mountain roads like those in Zhejiang, you have to keep it under 40. When hauling steel coils, I don't dare exceed 70 km/h—emergency braking could send the coils crashing through the cab. Reducing speed by 10 km/h in rainy conditions is standard practice due to poor visibility and slippery roads. Extra-long container trucks need to be especially cautious on national highways; some county roads have a 30 km/h speed limit, and tree branches on curves can scrape the top of the trailer. Fleet dispatchers often remind us: it's better to arrive late than not at all.
