Some of the most effective safety rules are also the simplest: wear a belt, put the phone away, strap children in properly, and stop when you are tired. These come up often on the theory test because they save more lives than almost anything else a driver does, and the rules are precise.
Seatbelts — everyone, every trip
- Seatbelts must be worn by the driver and all passengers, in the front and the back, wherever belts are fitted. Not wearing one is a €120 fixed charge and 3 penalty points (2026).
- The driver is legally responsible for ensuring passengers under 17 are properly restrained. For adult passengers, each adult is responsible for themselves — but a good driver will not move off until everyone is belted.
- Belts work with the car's crumple zones and airbags. In a crash an unbelted person is thrown forward with enormous force and can injure or kill others in the car as well as themselves. A belt is designed to spread that force across the strong parts of the body.
Child restraints
Children need protection sized to them, not just an adult belt:
- Children under 150 cm tall or under 36 kg must use a child restraint (seat or booster) suitable for their height and weight.
- Rear-facing seats must never be used in a front seat protected by an active airbag — a deploying airbag can be fatal to a rear-facing infant. Disable the airbag or place the seat in the back.
- The safest place for a child restraint is generally the back seat, correctly fitted and tightly secured.
Mobile phones and distraction
- Holding a mobile phone while driving is an offence — a €120 fixed charge and 3 penalty points (2026). It applies whether you are calling, texting, or scrolling — and even when stopped in traffic with the engine running.
- Hands-free is legal but still distracting. A phone conversation pulls your attention off the road even when both hands are on the wheel; the safest choice is to deal with calls before you set off or after you stop.
- Distraction is wider than phones: eating, arguing, tuning the radio, using a satnav, or turning to talk to passengers all steal attention. Set up satnav and music before you drive.
- Taking your eyes off the road for even a couple of seconds at speed means driving "blind" for a long distance — at 100 km/h, two seconds is over 50 metres travelled without looking.
Fatigue
Tiredness is a form of impairment the test treats seriously:
- It slows reactions and judgement much like alcohol, and can cause micro-sleeps — brief seconds of sleep you may not even notice.
- The warning signs are heavy eyelids, drifting in the lane, missing signs and yawning.
- The only real cure is sleep. On a long drive, plan regular breaks (roughly every two hours), and if you feel sleepy, stop somewhere safe and rest — a short nap and a caffeine drink buy time, but only rest fixes it.
### Exam focus - Belts for everyone, front and back. The driver is responsible for passengers under 17. - Children under 150 cm / 36 kg need a suitable child restraint; never a rear-facing seat in front of an active airbag. - Holding a phone while driving is an offence (fine + points), even stopped in traffic; hands-free still distracts. - Set up satnav/music before moving. - Fatigue is like alcohol; the only cure is rest — break roughly every 2 hours.
