Important traffic signs when towing a trailer (Part 3)
In the last two posts on the topic of traffic signs for towing a trailer, we have already introduced you to a few very important road signs and traffic signs that you should definitely pay attention to when towing a trailer. There are a handful of other traffic signs that we don’t want to leave out.
Traffic signs for vehicle combinations
Although the following traffic signs are relevant for towing a trailer, they only apply if the combination weighs more than 3.5 tons and the towing vehicle is neither a bus nor a car. So let’s assume that you mostly travel with a car and trailer, then these traffic signs are only important for you if your vehicle combination is particularly heavy. Again and again, drivers are unclear as to whether the following signs are relevant to them or not. In the following we summarize the most important information about the traffic signs for vehicle combinations.
The prohibition sign for trucks
The round prohibition sign shows a truck and states that a general driving ban applies to all motor vehicles with a permissible total weight of more than 3.5 tons. The sign also applies to trailers and their towing vehicles. The only exceptions are cars and buses. So if your motor vehicle is heavier, you will not be allowed to drive through after this sign.
Prohibition sign for heavy vehicles
Based on the actual mass of a motor vehicle, this round prohibition sign indicates how heavy a
vehicle may be in order to continue driving on the affected road. However, the plate refers to the actual mass (what the vehicle actually weighs), not the gross vehicle weight rating (what the vehicle is allowed to weigh). If you are traveling with a vehicle combination, for example with a trailer, then the weight of the individual vehicles is relevant, not the weight of the combination.
The length of your vehicle on traffic signs
The last traffic sign with a red frame is about the length of your vehicle. Pictured is a truck as well
an indication of its length. The sign states that you would need to consider the actual length of the entire vehicle combination. If your team is longer than indicated on the sign, then you are not allowed to drive into the street. If you continue to drive, it may for example be the case that you will not be able to turn around in an emergency or that curves are too narrow for you. As with the other signs, a fine will be imposed for disregarding the sign.
As the driver of a trailer, you must keep an eye on the traffic sign for narrow lanes, especially if your trailer is wider than your towing vehicle. In this case, drive a little more carefully into the bottlenecks or danger spots, drive slowly and use your side mirrors.
The traffic sign for uneven roads is important for you as a driver, because bumps in the road can cause the load to behave differently than usual. The load could come loose or start moving. In both cases, this also influences the handling of the vehicle combination. This is just one of the reasons why it is very important to always secure your cargo well. You can read about how best to do this in
to adjust the driving style accordingly. When a trailer starts to slide, it can have very different effects. If the trailer simply slides forward, you as the driver must ensure that you also use the engine brake when braking. The reason is that your car will also slide more, since the weight of the trailer exerts additional force on the vehicle from behind. If the trailer shears out and slides sideways, dangerous situations can quickly arise. It is important for you to remain as calm as possible and to avoid hectic braking and steering maneuvers in any case.
