How much can I drink before driving in Czechia?
Nothing — Czechia enforces zero tolerance (0.0 ‰). The 0.24 ‰ measurement margin is a technical correction of the breathalyser, not a "free beer". Sanctions escalate: up to 0.3 ‰ a fine of CZK 7,000–25,000 plus a 6–18 month driving ban (no points); 0.3–1 ‰ the same plus 6 penalty points; above 1 ‰ it is a criminal offence — up to a year in prison and a ban up to 10 years. Morning-after residual alcohol counts exactly the same — after a party, leave the car.
📋 The rules
- 0.0 ‰ — zero tolerance for drivers of all vehicles
- Up to 0.3 ‰: fine CZK 7,000–25,000, ban 6–18 months
- 0.3–1 ‰: the same + 6 penalty points
- Above 1 ‰: criminal offence — up to 1 year prison, ban up to 10 years
- Refusing the test = treated like a reading above 1 ‰
🔓 Exceptions
- The 0.24 ‰ device margin — a technical correction, not a permitted limit
- Non-motorised boats: 0.5 ‰; cyclists get fines but no points
⚠️ Penalties & fines
Misdemeanour: CZK 7,000–25,000 + 6–18 month ban (+6 points from 0.3 ‰). Crime above 1 ‰: up to 1 year prison, monetary penalty, ban up to 10 years. Crash while under the influence: your insurer recovers the payout from you.

❓ Frequently asked
Can I have one beer?
No. The limit is 0.0 ‰ — a single beer puts you in misdemeanour territory.
What is the 0.24 ‰ margin?
Only a technical correction of breath measurement — not a permitted level you can rely on.
When is alcohol gone after a night out?
The body clears roughly 0.1–0.15 ‰ per hour — after five beers you may not be sober even at 8 a.m.
What if I test positive in the morning?
Residual alcohol is judged exactly like evening driving — same fines and points.
Can I go to prison?
Above 1 ‰ yes — endangerment under the influence carries up to 1 year, more if you cause injury.
