Winter Tyres in Czechia 2026: Rules from 1 November, Tread Depth and Fines
Popular
In Czechia, winter tyres are compulsory from 1 November to 31 March whenever there is a continuous layer of snow, ice or frost on the road, or when such conditions can be expected given the weather. On roads marked with the “Zimní výbava” (winter equipment) sign they are required in that period regardless of the weather. Cars up to 3.5 tonnes need at least 4 mm of tread, and the fine is up to 2,000 Kč on the spot or up to 2,500 Kč in administrative proceedings.
Around Prague checked these rules against Act No. 361/2000 Coll. (§40a and §40c) and Czech Police guidance on 21 October 2026.
When winter tyres are mandatory
The rule comes from §40a of the Czech road traffic act (Act No. 361/2000 Coll.). It is not a blanket date-based obligation: between 1 November and 31 March you must have winter tyres if the road is covered with snow, ice or frost, or if you can expect it on your route. In practice, police treat cold mornings with frost as such conditions, so most drivers simply switch tyres before 1 November.
The exception is the “Zimní výbava” road sign (a white car with a snowflake on a blue background). It is common on mountain roads and some motorway sections. On a road with this sign, winter tyres are compulsory throughout the 1 November – 31 March period, even on a dry, sunny day.

Which tyres count as winter tyres
Czech rules accept tyres marked M+S (or M.S, M/S, MS). EU rules require manufacturers to put the Alpine symbol (a mountain with a snowflake, “3PMSF”) on new winter tyres, but the Czech Ministry of Transport has confirmed that this applies to manufacturers, not drivers: older M+S tyres remain legal in Czechia. All-season tyres with the M+S marking also count.
Driving abroad is different. Germany has required the 3PMSF symbol since 1 October 2024, so M+S tyres without the snowflake are no longer enough there in winter conditions. If you are driving to Germany, check the sidewall.
Tread depth: why 4 mm matters
For cars up to 3.5 tonnes the legal minimum for winter tyres is 4 mm. Czech Police point out that a tyre worn down to the legal minimum needs a braking distance up to 50% longer than a new one. The easy check is a tread depth gauge or the wear indicators in the grooves. Tyres are worth changing once temperatures stay below about 7 °C, when summer rubber hardens and loses grip.
Fines and insurance
Police can fine you up to 2,000 Kč on the spot; if the case goes to administrative proceedings, the fine is up to 2,500 Kč. The bigger risk is insurance: under comprehensive cover (havarijní pojištění) the insurer can cut the payout if it shows the accident was directly linked to unsuitable tyres. Compulsory third-party liability insurance still pays the other party, but the insurer may seek recourse from you. See our guide to car insurance in Czechia.
Frequently Asked Questions (FAQ)
Do I need winter tyres in Czechia from 1 November?
Only if there is snow, ice or frost on the road or it can be expected, or if you drive on a road with the “Zimní výbava” sign. In practice most drivers switch before 1 November.
Are all-season tyres legal in winter in Czechia?
Yes, if they carry the M+S (or M.S, M/S, MS) marking and have at least 4 mm of tread.
Can I have winter tyres on the drive axle only?
No. Czech law (§40c) requires the same type of tyre on all four wheels.
Do rental and foreign-registered cars have to follow the rule?
Yes. The rule applies to every vehicle driving on Czech roads. Rental companies in Czechia fit winter tyres for the season; check this when you book.
Can I drive on winter tyres in summer?
The law does not ban it, but winter tyres wear fast and brake worse on warm, dry roads, so it is not recommended.
