The question of where exactly the left side of the car is located is often a source of confusion for newbies, especially given the variety of steering columns on the global market. It would seem like elementary geometry, but in reality, drivers often make mistakes, confusing the driver's side and the passenger's side, which leads to oddities when ordering spare parts or filling out documents about an accident.
Definition of parties is based solely on the position of the person sitting behind the wheel and looking in the direction of travel of the vehicle. If you are in the driver's seat, then everything that is on your left hand belongs to the left side of the body, and your right hand points to the opposite side.
This axiom works regardless of which side the steering wheel is located on. Even if you are sitting in right-hand drive in a Japanese car, the logic of reference does not change: the left side remains left, the steering wheel is simply shifted to the right relative to the central axis of the cabin.
Official position of traffic rules and GOST
In the regulatory documents of the Russian Federation, including Traffic Rules and technical regulations, there is no separate paragraph that would say “the left side is...”, however, the logic of constructing the entire road infrastructure implies orientation in the direction of travel. Vehicle design always viewed from a top view, where the top is the front and the bottom is the back.
According to GOST R 51709-2001, which regulates the requirements for the technical condition of vehicles, the numbering and designation of sides are also based on the driver’s position. This is critically important when designing accident diagrams, where the traffic police inspector must clearly understand which side the impact occurred.
⚠️ Attention: When filling out a European protocol or explanatory note, never write “from the driver’s side” if you are in the passenger seat. Use only the terms "port" or "starboard" to avoid legal conflicts.
It is also worth considering international standards. In countries that drive on the left (UK, Japan), the physical location of the controls is shifted, but the terminology "left side" remains tied to the geometric axis of the car, and not to the position of the steering wheel.
The problem of right-hand drive cars
The greatest difficulties in determining the sides arise for owners of cars imported from countries with left-hand traffic. In such machines, for example Toyota or Nissan Japanese assembly, the driver's seat is on the right, but this does not make the right side left.
Imagine that you are sitting behind the wheel of such a car. Your left hand still points to the driver's door (which in this case is the right side in the direction of travel for oncoming cars, but for you it is the left side of the cabin). However, if you look at the car from the outside, standing in front of it, then port side will be on your right side as an observer.
It is important to distinguish between “car side” and “driving side”. The left side of the car is a constant geometric parameter. But the passenger disembarkation side may vary depending on the country of operation. In Japan you will disembark the passenger on the left side (sidewalk), in Russia - on the right side (roadway).
When ordering body parts (fender, door, bumper), always check with the manager: “Is the side indicated in the direction of travel or on the driver’s side?” For right-hand drive cars, this is a common reason for returns.
When selling such a car, the documentation often indicates the steering feature, but the geometric parameters of the body remain standard. This is important to consider when insurance caseswhen an accurate description of damage is required.
Spare parts markings and catalogs
Automotive catalogs and spare parts stores use a single coding system to eliminate errors when ordering. Side numbering strictly tied to the direction of movement forward. This is especially true for paired elements: headlights, mirrors, suspension arms and doors.
Typically, electronic catalogs use the following logic:
- 🚗 LH (Left Hand) - indicates the left side of the car (in the direction of travel).
- 🚙 RH (Right Hand) - indicates the right side of the car.
- 🛠️ LHD (Left Hand Drive) - a car with a left-hand drive.
- 🛠️ RHD (Right Hand Drive) - a right-hand drive car.
Confusion between LH (side) and LHD (handlebar type) is the most common mistake when independently selecting parts via the Internet. If you need a left mirror for a right-hand drive car, you are still looking for a part marked LH, since geometrically this is the left corner of the body.
In addition, there are symmetrical and asymmetrical parts. If the part is symmetrical (such as some stabilizer bushings), the side may not matter. But for asymmetrical nodessuch as steering knuckles or door handles, an error in one direction will result in impossible installation.
What to do if the part does not fit the fasteners?
If you purchased a part with the correct LH/RH markings, but it does not fit, check the year of manufacture and the specific modification. Sometimes manufacturers change fasteners within the same model year (restyling).
Designation table
For ease of perception of information, we summarize the main notations in a single table. This will help you quickly navigate when reading technical documentation or communicating with mechanics.
| Designation | Decoding | Where is it located (looking forward from the cabin) | Part example |
|---|---|---|---|
| LH | Left Hand | Driver's left | Left front fender |
| RH | Right Hand | Driver's right | Right headlight |
| LHD | Left Hand Drive | Steering wheel on the left | Europe, USA, Russia |
| RHD | Right Hand Drive | Steering wheel on the right | Japan, UK, Australia |
The use of these abbreviations is universal for most of the world's automakers, be it Volkswagen, Hyundai or BMW. Knowing this table will save you time and money when ordering rare parts.
Nuances when repairing and painting
When contacting a body service, it is important to correctly indicate the damage area. If you tell a technician “scratch on the left,” he may get the wrong idea while standing in front of the car. Always specify: “Left fender in the direction of travel” or “Left door on the driver’s side.”
B diagnostic cards and defect detection reports, the parties are numbered or marked with letter codes. An error in determining the side may result in a part with incorrectly positioned holes or fasteners being installed on the vehicle.
⚠️ Attention: When ordering glass (windshield or side), the side is critical only for side windows. The windshield is usually symmetrical, but there are exceptions for models with cameras or rain sensors offset in a certain direction.
Also when polishing or applying protective coatings, craftsmen often work section by section. A correct understanding of the zones allows you to accurately estimate the scope of work and the cost of the service, especially if the damage is localized to only one side.
☑️ Check before ordering spare parts
Visual guidelines for beginners
If you are just starting your driving experience and are afraid of getting confused, use simple visual anchors. The most reliable way is to imagine that you are sitting behind the wheel and looking at the road. Your left hand points to the side of the road (in countries with right-hand traffic) and your right hand points to the oncoming lane.
Another method is to navigate using the dashboard. The speedometer and tachometer are usually located in front of the driver. Everything to the left of the center axis of the instrument panel (including the fuse box or storage compartment) belongs to the left side of the cabin.
For external elements, you can use the "traversal" method. If you stand in front of the bumper and begin to walk around the car counterclockwise, you will be driving on the left side. If it's clockwise, it's right. This helps to visually divide the body into two halves during inspection.
The main rule: Sit in the driver's seat, look ahead. Left hand = left side of the car. This rule works for 100% of vehicles.
Does the side of the car affect the cost of compulsory motor insurance?
The side itself (left or right) does not affect the base rate. However, if the car is right-hand drive (RHD), some insurance companies may apply increasing coefficients due to accident statistics or the complexity of risk assessment, although in the Russian Federation there are no legal restrictions on the operation of right-hand drive.
Is it possible to move the steering wheel from left to right?
Theoretically, this is possible, but in practice it requires a complete rework of the dashboard, wiring, steering rack and pedal assembly. In Russia, such a rework will require a very complicated certification procedure in a laboratory and registration of changes with the State Traffic Safety Inspectorate, which is not economically feasible.
Why do catalogs sometimes write "Driver Side"?
The term "Driver Side" is used as a synonym for the side of the steering wheel. In left-hand drive cars Driver Side = LH, in right-hand drive cars Driver Side = RH. Be careful: if the catalog is American, it almost always means LHD, so Driver Side will be on the left.
How to determine the side if the car is standing without wheels?
The absence of wheels does not change the geometry of the body. Find the front part (where the headlights and engine are) and imagine that you are sitting inside. The logic for determining the sides remains the same regardless of the configuration or condition of the chassis.
