Gadlane alcohol breathalysers France 2 pack – single-use disposable tests
Heading to France or just want a quick check before you drive home? These compact, pocket-sized breathalyser tests give a clear, indicative result so you can make safer choices. They’re designed for the lower French roadside limit of 0.25 mg/L (breath) — that’s the same as 0.5 g/L in blood. Handy to keep in the glovebox for a bit of peace of mind.
Quick, no-fuss checks
Each test is single-use and sealed until needed. Give the tube a steady blow as instructed, wait roughly 3–4 minutes and watch the crystals. If they turn red, that indicates your breath alcohol is at or above the French limit — in which case, don’t drive. No faff, no complicated setup.
Where these tests fit in
- Ideal for UK motorists travelling to France and other European countries with lower limits.
- Great for a quick sanity check after a night out, before a long drive home, or for informal workplace checks where permitted.
- Indicative only — these tests can’t be used to contest an official police test or measurement.
Practical things to know
The pack contains two NF-approved single-use breathalysers certified to NFX 20-702:2016. Typical shelf life is around two years — store them somewhere cool and dark, out of direct sunlight, and use between 10°C and 40°C. Each test is for one use only; please dispose of used tests responsibly. Keep them well away from children and pets, and avoid skin contact with the crystals — if contact occurs, rinse thoroughly with water.

These tests aren’t a substitute for official kit, and breath readings can continue to rise for up to an hour after drinking. If you’re in any doubt, the safest choice is simply not to drive. In short: a small, inexpensive way to reduce risk and avoid a ruinous mistake — well worth having when you’re travelling abroad.
