The issue of priority on the road often causes heated debate between both new and experienced road users. Many drivers mistakenly believe that vehicle size or its mass directly affect rights of way. There is a persistent myth that heavy equipment always takes priority due to its inertia and difficulty in maneuvering. However, the traffic situation is governed by completely different principles.
In fact, Traffic rules (Traffic Regulations) do not contain a direct indication that the truck is always right, and the passenger car must yield simply due to its size. The advantage in traffic is determined not by the type of body, but by the specific road situation, signs and signals of the traffic controller. Understanding these nuances is critical to preventing accidents and fines.
In this article we will analyze in detail all scenarios where the trajectories of cars and trucks intersect. You will learn how to correctly interpret the rules when changing lanes, at intersections and when overtaking. We will also touch on the topic of “blind spots” and the psychological pressure that large vehicles can exert on the driver of a small car.
Basic principles of priority according to traffic rules
The foundation of safe driving is knowledge of the section of the traffic rules concerning the order of travel. Advantage (priority) - this is the right to priority movement in the intended direction in relation to other road users. If we talk about the confrontation between “passenger cars and trucks,” then in a vacuum, without signs and traffic lights, they are absolutely equal.
However, equality of rights does not mean equality of opportunity. Driver truck limited by dimensions, braking distance and visibility. The driver of a passenger car is more maneuverable, but less noticeable. The rules require all traffic participants to act in such a way as not to create interference, but if a controversial situation arises, a hierarchy of signs and signals comes into force.
The key point is that there is no automatic priority for any of the participants. Neither the weight of 20 tons nor the comfort of the sedan gives the right to ignore the "Give way" signs. In controversial situations where there are no signs, the “interference from the right” rule often applies, but it also has many exceptions, which we will discuss below.
In the traffic rules there is no concept of “weight advantage” - a truck and a passenger car are legally equal, unless signs say otherwise.
The situation at intersections: equal and unequal roads
An intersection is a place where conflicts between different types of transport most often occur. If the intersection is controlled, then the question “who has the right of way” disappears by itself: everything is controlled traffic light or traffic controller. In this case, the truck must yield to the passenger car if the light is red, and vice versa.
Difficulties begin at unregulated intersections. This is where the concept of road equivalence comes into play. If you are approaching an intersection with a car, and a truck from the same road (or a road with a similar surface) exits to your right, then the advantage is on the truck side solely because it is on the right. This is the rule “interference on the right” (clause 13.11 of the traffic rules).
However, if a truck leaves a dirt road onto an asphalt road where you are, then it must yield, regardless of its size. Road surfaces and priority signs (Main Road, Give Way) are critical. Ignoring these signs by large vehicles often leads to serious accidents due to inertia.
It is worth noting the psychological aspect. Even with priority, the driver of a passenger car is often forced to give way to a “truck” going to ram. This is not stated in the laws of physics or traffic rules, but is dictated by the instinct of self-preservation. A collision with a light car means a bumper repair for a truck; for a passenger car it means total destruction.
Rules for changing lanes and changing lanes
One of the most common questions is: who should give in while rebuilding at the same time? Let's imagine a situation: you are changing lanes in a passenger car into the left lane, and a truck is changing lanes to your right in the same lane. According to paragraph 8.4 of the traffic rules, when changing lanes, the driver must give way to vehicles moving in the same direction without changing the direction of movement.
If both cars change lanes at the same time (you go to the right, he goes to the left, or both in one row from different lanes), then the one on the right has the advantage. In the case of the truck on your right, technically he is right. But here lies the main trap for car drivers.
The truck has huge blind spots. The truck driver may simply not see your small car in the side mirrors, especially if you are close to the cab. An attempt to “slip” between two trucks or to wedge in front of one when changing lanes often ends in being side-swiped or pushed to the side of the road.
- 🚛 Invisibility zone: the truck does not see the car if it is close to the front bumper or far behind diagonally.
- 🔄 Turning radius: When changing lanes before an intersection, the truck needs more space and can take up two lanes.
- 🛑 Inertia: the truck cannot brake or stop suddenly if you suddenly change lanes in front of it.
Never change lanes next to a truck unless you can see the driver's eye in his side mirror. If you don't see him, he doesn't see you.
Overtaking: when you can get ahead and when you can’t
Overtaking a truck is a high-risk maneuver. Many drivers of passenger cars believe that their acceleration dynamics give them the moral right to aggressively overtake. However, overtaking rules are strictly regulated and do not make any allowances for a “small car”.
The advantage when overtaking is always with the one who has already started the maneuver. If a truck starts to overtake another vehicle, you must slow down and give way to it, even if you are driving a powerful sports car. Completing overtaking a truck requires significantly more time and distance than overtaking a car.
It is critical to consider limited visibility in front of the truck. You don't see what's happening in the oncoming lane until you're level with the cab. Driving into oncoming traffic behind a truck or hoping it will slow down is one of the main causes of head-on collisions.
Why can't you "pull up" to a truck when overtaking?
There is a wind tunnel effect. When approaching a large vehicle at high speed, a vacuum of air occurs between the vehicles, which can literally “suck” a passenger car under the wheels of a truck or sharply destabilize its directional stability.
It is also worth remembering that overtaking is prohibited in certain areas. If you see a truck start to flash its left turn signal or move to the left, do not try to cut it off on the right. Most likely, it is preparing to turn or go around an obstacle, and its dimensions may hide the real situation from you.
Driving in heavy traffic and congestion
In city traffic or a traffic jam on the highway, the relationship between cars and trucks is built on mutual respect and understanding of the physics of the process. Trucks have limited maneuverability. They find it harder to get into tight pockets, harder to take off on hills, and harder to brake.
The question often arises: is it necessary to start a truck when merging traffic (for example, from an acceleration lane on a highway)? Technically, if the truck is already in the lane, you must yield. If he is just leaving the acceleration lane, and you are moving along the main lane, then you have priority. But common sense dictates skipping heavy vehicles so as not to risk the integrity of your car.
There is an unspoken rule of "courtesy on the road." If you see a truck trying to change lanes and you have the ability to safely ease off the gas and let it go, do it. It will take a couple of seconds, but it can save a life. A truck with a full load of 20 tons will not be able to react as quickly as a car.
| Situation | Who has the right of way (traffic rules) | Recommendation for passenger cars |
|---|---|---|
| Changing lanes of a truck on the right | Truck (clutter on the right) | Give in, don't take risks |
| Changing lanes of cars on the right | Passenger car (interference on the right) | Make sure you are seen |
| Narrowing of the road | Give way sign | Follow the sign |
| Leaving the dirt road | The one on the asphalt | Keep speed, be careful |

Features of winter driving and slippery roads
Winter makes its own adjustments to the distribution of priorities. On a slippery road braking distance truck increases significantly. Even if according to the rules you have the right of way (for example, the light is green), entering the intersection in front of a speeding truck is suicide.
In winter conditions, passenger vehicles should be especially careful around snowplows and trucks that may suddenly move sideways due to ruts or ice. The advantage in this case is given to the one who can stop his car, and not to the one who is right according to the signs.
It is also worth considering the “mess” of snow and mud that truck wheels kick up. This dramatically reduces visibility. If a truck is following you, it is better to increase your distance or carefully change lanes so that it can overtake you, since in its “fog” you become invisible to others.
⚠️ Attention: In winter, never brake sharply in front of a truck, even if it breaks the distance. Its brakes may not work on ice, and it will simply crush your car. It’s better to gradually increase the distance or move to the side.
Psychology of interaction and "Road politeness"
The laws of physics and traffic rules are one thing, but the human factor is another. Truck drivers are professionals who spend 10-12 hours behind the wheel. They know their limitations and are often annoyed by cars cutting them off. Aggressive behavior of a passenger car driver (checkers, sudden lane changes) can provoke a truck driver to respond or simply lead to him simply not being noticed.
There is a concept of "cargo etiquette". Truckers often flash their hazard lights as a sign of gratitude for giving way or to warn of danger on the highway. Mutual understanding on the road reduces tension. A passenger car that drives predictably and respectfully attracts less aggression and attention from larger vehicles.
Remember that in the event of a truck accident, even if you are 100% in the right, the consequences will be more severe for you. Therefore, the principle of “GDD” (Give Way to a Fool) in the case of trucks is transformed into “Give Way to Tonnes”.
⚠️ Attention: If you see that a truck is starting a maneuver (turning, changing lanes) without the turn signal on or late, do not try to prove that you are right and get through. The inertia of a multi-ton machine is stronger than your rights.
Frequently asked questions (FAQ)
Does a truck have the right of way when exiting a secondary road?
No, it doesn't. If a truck leaves a secondary road (marked with signs 2.4 “Give way” or 2.5 “No driving allowed”), it must yield to all vehicles moving on the main road, regardless of their type. Passenger cars on the main road have priority.
Who must yield when changing lanes on a multi-lane road at the same time?
According to traffic rules, when simultaneously changing lanes of vehicles moving in the same direction in adjacent lanes, the driver must give way to the vehicle on the right. If a truck changes lanes to the right of a passenger car, it formally has the advantage.
Is it possible to overtake a truck if it is stopped at a pedestrian crossing?
Overtake a vehicle that has stopped or is slowing down in front of a pedestrian crossing, strictly prohibited (clause 11.5 of the traffic rules). You are also required to slow down or stop, since due to the size of the truck the pedestrian is not visible. Passing a truck into the oncoming lane in such a situation is a gross violation.
Is it true that trucks are prohibited from driving in the left lane?
On roads with three or more lanes for traffic in a given direction, trucks with a permissible maximum weight of more than 2.5 tons are prohibited from occupying the leftmost lane. However, this rule does not apply if there are turn lanes on the left or if driving in other lanes is impossible due to repairs or an accident.
