Dipped beam in darkness and poor visibility
Dimlicht
Dipped beam is required whenever it is dark or visibility is otherwise reduced, such as in rain, mist or twilight. It remains the standard light for ordinary driving conditions.

Understand Dutch vehicle lighting rules for the theory exam
Lighting questions test whether you know which lights are required in darkness, poor visibility, fog and breakdowns, and which lights are never enough on their own.

When must you use lights while driving in the Netherlands?
Dutch drivers must use dipped beam headlights (dimlicht) whenever it is dark or visibility is otherwise poor, such as in heavy rain or fog. Daytime running lights (dagrijverlichting) may switch on automatically in daylight, but they are not a substitute for dipped beam once conditions worsen.
Main beam (grootlicht) gives better forward visibility but must be dipped in good time for oncoming traffic and for vehicles you are following, to avoid dazzling other drivers. Front and rear fog lights have their own separate visibility thresholds and are not meant for everyday use.
Beyond the basic headlight rules, the theory exam also covers parking lights, hazard lights, tunnel lighting, and the lighting obligations for trailers and bicycles, since all of these appear regularly in real driving situations.
What you need to understand
Daytime running lights are not enough by themselves
Dagrijverlichting
Daytime running lights work well in clear daylight but usually illuminate less than dipped beam and do not always include rear lights, so you must switch to dipped beam once conditions worsen.
Main beam and dazzling other drivers
Grootlicht
Main beam gives extra range on dark, unlit roads, but must be dipped in good time before oncoming traffic and before you catch up with a vehicle ahead, to avoid dazzling other drivers.
Front fog lights
Mistlicht voor
Front fog lights may be used when visibility drops to roughly 200 metres or less, giving a wider, lower beam that cuts through fog or heavy rain better than dipped beam alone.
Rear fog light has a stricter threshold
Mistlicht achter
The rear fog light should only be switched on when visibility falls to around 50 metres or less, since its intensity can dazzle following traffic if used too soon.
Parking lights are not for driving
Stadslicht
Parking lights (stadslicht) may be used while a vehicle is stationary at the kerb in certain conditions, but they do not provide enough illumination or visibility for actually driving.
Hazard lights for breakdowns and warnings
Alarmlichten
Hazard lights are used when a vehicle has broken down, is obstructing traffic, or to warn following traffic of a sudden queue or danger ahead, such as on a motorway.
Lighting inside tunnels
Tunnelverlichting
Signs at tunnel entrances generally require dipped beam to be switched on for the length of the tunnel, even during the day, regardless of daytime running lights already being on.
Trailers and bicycles need their own lights
Aanhangwagen- en fietsverlichting
A trailer must show its own rear lights and reflectors matching the towing vehicle, and a bicycle used after dark needs a white or yellow front light and a red rear light.
Use this five-step lighting check
- 1
Is it dark or is visibility otherwise reduced?
If so, dipped beam is required regardless of whether daytime running lights are already on.
- 2
Is there oncoming traffic or a vehicle ahead of me?
Dip main beam in good time to avoid dazzling drivers coming towards you or travelling in front of you.
- 3
How far can I see ahead of me right now?
Use this distance to judge whether front fog lights, and separately rear fog light, are appropriate.
- 4
Am I stopped, broken down, or warning others of danger?
Parking lights, hazard lights or both may be needed depending on why and where you have stopped.
- 5
Am I entering a tunnel or towing a trailer?
Switch on dipped beam for tunnels and check that a trailer's own lights and reflectors are working.
This sequence is a consistent way to judge which lights a situation calls for, not a script to recite from memory.

For a stationary vehicle, not for driving.
Alarmlichten

For breakdowns, obstructions or warning of a queue.
Tunnelverlichting
Tunnel lighting rule
Dipped beam required through tunnels, day or night.
Common mistakes learners make
Relying on daytime running lights after dark
Daytime running lights are designed for clear daylight and often lack rear illumination, so dipped beam is still required once it grows dark.
Leaving main beam on for oncoming traffic
Failing to dip in good time can dazzle oncoming drivers and briefly blind them, creating a real safety risk rather than just a rule violation.
Switching on the rear fog light too early
Using the rear fog light before visibility genuinely drops to around 50 metres can dazzle following traffic and hide your brake lights.
Treating parking lights as sufficient for driving
Parking lights are meant for a stationary vehicle in specific conditions, not for actually driving, since they provide far less illumination.
Forgetting dipped beam inside tunnels
Even with daytime running lights active, signs at tunnel entrances generally require dipped beam headlights for the full length of the tunnel.
Ignoring trailer lighting before a journey
A trailer with faulty or missing rear lights is both an offence and a real hazard, since following traffic relies on it to judge your vehicle's length and braking.
Not using hazard lights to warn of a sudden queue
On motorways especially, switching on hazard lights briefly to warn traffic behind you of a sudden slowdown can prevent a rear-end collision.
Work through the situation step by step
Scenario 1 — Driving into thickening fog
- Situation
- You are driving on a rural road as fog rolls in, and you estimate you can now see only about 40 metres ahead of you.
- What to inspect first
- Judge the current visibility distance before deciding which lights beyond dipped beam are appropriate.
- Correct action
- Switch on both front and rear fog lights, since visibility has fallen below the roughly 50-metre threshold for the rear fog light.
- Explanation
- Front fog lights help below about 200 metres, but the rear fog light should wait until visibility is around 50 metres or less, which this scenario has reached.
- Relevant principle
- The rear fog light has a stricter visibility threshold than the front fog light.
Scenario 2 — Oncoming traffic on an unlit road
- Situation
- You are driving with main beam on an unlit rural road at night, and a car appears in the distance travelling towards you.
- What to inspect first
- Estimate the distance to the oncoming car and recognise that main beam will soon dazzle its driver if left on.
- Correct action
- Dip your headlights to dipped beam well before the vehicles meet.
- Explanation
- Main beam must be dipped in good time for oncoming traffic to avoid dazzling the other driver, well before the point where dazzling would occur.
- Relevant principle
- Main beam is dipped for oncoming traffic in good time, not at the last moment.
Scenario 3 — A breakdown on the hard shoulder
- Situation
- Your car breaks down and you manage to bring it to a stop on the hard shoulder of a motorway during the day.
- What to inspect first
- Recognise that the vehicle is stationary and obstructing normal use of the shoulder, which following traffic needs to notice.
- Correct action
- Switch on your hazard lights while you and any passengers move behind the barrier if possible.
- Explanation
- Hazard lights warn approaching traffic that your vehicle is stopped and not moving normally, which is essential even in daylight on a fast road.
- Relevant principle
- Hazard lights signal an obstruction or breakdown, day or night.

Dipped beam (dimlicht) is required whenever it is dark or visibility is otherwise poor, such as in heavy rain, mist or twilight, regardless of whether daytime running lights are on.
No. Daytime running lights are designed for clear daylight and often provide less illumination and no rear lights, so dipped beam must be used once it is dark.
Dip your main beam in good time before meeting oncoming traffic and before catching up with a vehicle ahead, so you do not dazzle the other driver.
Front fog lights are appropriate when visibility drops to roughly 200 metres or less, while the rear fog light should wait until visibility is around 50 metres or less.
No. Parking lights (stadslicht) are intended for a stationary vehicle in certain conditions and do not provide enough light or visibility for driving.
Generally yes. Signs at tunnel entrances usually require dipped beam headlights for the length of the tunnel, even in daylight.
