How much can I drink before driving in Czechia?
Nothing — Czechia enforces zero tolerance (0.0 ‰). The 0.24 ‰ measurement margin is not a free beer, only a technical correction of the breathalyser, and you cannot rely on it. 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 (§ 274 of the Criminal Code) — up to a year in prison and a ban of up to 10 years. Refusing the test is treated as a reading above 1 ‰, so declining to blow makes things worse, not better. The most underrated risk is the morning after: residual alcohol is punished exactly the same, because the body clears only about 0.1–0.15 ‰ per hour.
📋 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
- Refusing a breath or blood test brings no relief — it is treated as a reading above 1 ‰, that is, as a criminal offence
⚠️ Penalties & fines
Misdemeanour: CZK 7,000–25,000 and a 6–18 month driving ban, plus 6 penalty points from 0.3 ‰. Above 1 ‰ it is the crime of endangerment under the influence: up to a year in prison, a monetary penalty, a ban of up to 10 years and an entry on your criminal record that complicates employment. The biggest cost is rarely the fine, though: cause a crash while over the limit and your insurer pays the victim, then recovers the whole payout from you. Refusing the test saves nothing either — it is treated as a reading above 1 ‰.

❓ Frequently asked
Can I have one beer?
No. The limit is 0.0 ‰, so a single beer already puts you in misdemeanour territory with a CZK 7,000–25,000 fine and a driving ban. The 0.24 ‰ device margin is not a permitted level you can rely on.
What is the 0.24 ‰ margin?
It is only a technical correction of breath measurement built into the device — not a permitted limit and not guaranteed to you. Police can always order a blood test, where no such margin applies at all.
When is alcohol gone after a night out?
The body clears roughly 0.1–0.15 ‰ per hour and nothing speeds it up — not coffee, not a shower. After five beers you may still be over the limit at 8 a.m., and a morning check measures it just the same.
What if I test positive in the morning?
Residual alcohol is judged exactly like driving straight from the pub: same fines, same points, same ban. The fact that you slept since your last drink carries no weight at a roadside check.
Can I go to prison?
Above 1 ‰ yes — endangerment under the influence carries up to 1 year and a driving ban of up to 10 years. If you also cause a crash with injuries, the sentencing range rises considerably.
