Sign "SH" on the rear window of a car is one of the most discussed elements of road regulation in Russia. Many drivers still confuse it with the designation "U" (training vehicle) or completely ignore the requirement to install it. Meanwhile, the absence of this sign can result in a fine, and incorrect use can create an emergency situation on the road.
In this article we will analyze in detail what the sign means "SH" by car, who needs it according to current Traffic rules (traffic rules)how to glue it correctly and what nuances are important to consider in 2026. You will also find out what fines are provided for violations, and why traffic police inspectors are so picky about this seemingly small element.
Arguing about the need for a sign "SH" is possible endlessly, but the fact remains: its presence or absence directly affects traffic safety, especially in winter. After all, studded tires behave differently on the road than Velcro tires, and other drivers should be warned about this.
If you have just “changed” your car for the winter or, conversely, removed the studded tires in the spring, this article will help you avoid mistakes and not get fined. And for those who doubt the appropriateness of the sign, we will give accident statisticsassociated with improper use of studded tires.
What does the "Sh" sign on a car mean: official transcript
Sign "SH" - this is warning sign, which informs other road users that the vehicle is equipped with studded tires. The official name of the sign is "Spikes" (clause 8 Basic provisions for the approval of vehicles for operation).
B Russian traffic rules (last edition on 2026) sign "SH" is regulated as follows:
- 📜 Required for installation for all vehicles (cars, trucks, buses), if they have tires with studs.
- 🚗 Not required, if the car is “shod” in winter tires without studs (the so-called “Velcro”) or summer tires.
- ⚠️ Prohibited use sign "SH", if the car does not have studded tires, this is considered to be misleading other drivers.
It is important to understand that the sign "SH" - this is not just a formality, but security element. Studded tires have improved grip on ice, but at the same time increased braking distance on asphalt compared to Velcro. If the driver behind you doesn't know you have spikes, he might underestimate the distance and cause an accident.
Interesting fact: in some European countries (e.g. Finland or Norway) sign "SH" is not required, since studded tires are allowed there only in certain months, and all drivers by default assume their availability in winter. In Russia, where the choice between “spikes” and “Velcro” is left to the driver, the sign is required.
Who definitely needs the "Sh" sign in 2026: analysis of traffic rules
According to clause 8 of the “Basic provisions for the approval of a vehicle for operation” (addendum to traffic rules), sign "SH" must be installed on all vehicles, which have spikes on their wheels. This rule applies regardless of the time of year - even if you drive on studded tires in the summer (which in itself is not recommended), the sign must be in place.
Let's take a closer look at who necessarily need a sign "SH":
- 🚘 Passenger cars — if at least one wheel has spikes, the sign must be installed.
- 🚛 Trucks (including light-duty Gazelles) - the rule is the same.
- 🚌 Buses and minibuses - regardless of the number of passenger seats.
- 🏍️ Motorcycles and mopeds - if they have studded tires (which is extremely rare, but allowed).
But who is the sign "SH" not needed:
- ❄️ Drivers with winter tires without thorns (“Velcro”)
- ☀️ Drivers with summer tires (even if they are all-season, but without studs).
- 🚜 Owners of special equipment (tractors, excavators, etc.), if it is not intended for driving on public roads.
An important nuance: if you have different tires on axles (for example, Velcro in front, spikes in back), sign "SH" anyway required. Traffic regulations do not make exceptions for such cases.
If you bought a used car with studded tires, but are not sure whether there are studs on them, check this in a simple way: run your hand over the tread - the studs will be clearly felt.

Myths and misconceptions about the "Sh" sign: what is true and what is not
Around the sign "SH" There are many myths circulating. Let's look at the most common ones:
Myth 1: “The "Sh" sign is only needed in winter”
❌ Not true! Sign required all year round, if the car has studded tires. Even if you ride on spikes in the summer (which is not recommended), the sign must be in place.
Myth 2: “If the thorns are almost worn off, you don’t have to glue the sign”
❌ Not true! Traffic regulations do not make exceptions for “half-erased” spikes. If the tires were originally studded, a sign is needed, even if only indentations remain from the studs.
Myth 3: “The "Sh" sign can be attached anywhere - even on the bumper”
❌ Not true! The sign must be on the rear window (for cars) or rear of the body (for trucks). Bumper or door mount does not comply with traffic regulations.
Myth 4: “Traffic police inspectors do not check the "Sh" sign”
❌ Not true! Although cameras do not record this violation, inspectors at checkpoints and when stopping be sure to pay attention on the sign, especially in winter.
