🚨 Refusing an alcohol or drug test: is it really worse than a positive result?

Many drivers believe that refusing an alcohol or drug test is a way to avoid evidence.

In practice, this strategy often leads to more severe consequences than a positive result.

Here is what you need to know under Belgian road traffic law.

⚖️ 1) Legal basis: refusal is a separate offence

In Belgium, drivers are legally required to cooperate with:

a breath test or breath analysis for alcohol,
a saliva test or blood test for drugs.

❗ Refusing to undergo the test constitutes a criminal offence in itself, regardless of whether you were actually under the influence.

The refusal is treated as an attempt to avoid official findings.

📊 2) Refusal vs positive test: which is worse?

🔴 Refusal

Typically leads to:

mandatory court appearance,
driving ban (often significant),
criminal fine (plus surcharges),
possible additional measures (medical or psychological examinations).

Courts generally consider refusal serious, as it prevents objective verification.

🟠 Positive alcohol test

Sanctions depend on the level:

0.22 – 0.35 mg/l: administrative fine (usually no court)
0.35 – 0.65 mg/l: criminal level, possible driving ban
Above 0.65 mg/l: severe sanctions and longer disqualification

In some cases, a transaction or immediate settlement may be possible.

👉 In practice, refusal often leads to stricter and less flexible outcomes than many positive results.

⛔ 3) Immediate driving licence suspension

In both situations (refusal or serious positive result), the police may impose:

immediate licence withdrawal (typically 15 days),
extension by the public prosecutor,
possible longer driving ban ordered by the court.

For many drivers, the professional impact is immediate and significant.

📁 4) Criminal and administrative consequences

Possible consequences include:

criminal conviction,
high fines (plus additional surcharges),
driving disqualification,
mandatory medical and/or psychological examinations,
new driving tests,
insurance consequences,
possible professional difficulties.

⚖️ 5) Court practice and trends

In practice, courts often:

treat refusal as a deliberate obstruction,
impose systematic driving bans,
order additional assessments (medical or psychological),
apply stricter measures than for moderate alcohol levels.

The reasoning is simple: refusal prevents objective measurement and raises suspicion.

🚔 6) What to do during a police check?

If you are stopped:

✔ Stay calm and cooperative
✔ Follow police instructions
✔ Avoid confrontation or refusal
✔ Be aware that refusal usually worsens your legal position

If you have doubts about the procedure, this can be analysed afterwards — but refusal at the roadside is rarely a good strategy.

✔️ Key takeaway

Many drivers think refusal protects them.
In reality, it often leads to:
➡️ court proceedings
➡️ longer driving bans
➡️ heavier overall consequences

In most situations, refusal is legally riskier than a positive test.
