Rear fog lights (dimbakljus in Swedish) are powerful red lights designed to make your vehicle highly visible from behind during extremely poor weather conditions such as thick fog, heavy rain, or intense snowfall. While essential for safety when visibility is severely limited, their brightness can be dazzling to other drivers. The Swedish traffic regulations stipulate specific conditions for their use, making it a key topic for driving theory test preparation. Learners must understand both when to switch them on and, crucially, when to turn them off to avoid blinding others.
dimbakljus
Rear fog lights are bright red lights at the back of a vehicle, used to make it visible in severely reduced visibility conditions like dense fog or heavy snowfall.
Fog On, Clear Off: Remember to switch Rear Fog Lights ON in thick fog, and OFF as soon as visibility improves or others see you.

See how Rear fog lights appears in realistic driving situations relevant to Sweden. These examples explain correct behaviour, safety implications, and how Rear fog lights connects to Swedish driving theory exam questions.
You are driving on a rural road in Sweden during an extremely dense fog, where you can barely see 20 meters ahead, and regular tail lights are not cutting through.
Switch on your rear fog lights (dimbakljus) immediately to ensure your vehicle is clearly visible to any traffic approaching from behind.
In such severely reduced visibility, normal tail lights are insufficient. Rear fog lights provide the necessary intensity to penetrate the fog, making your vehicle easily detectable by following drivers and significantly reducing the risk of a rear-end collision, which is crucial for road safety.
You have been driving with your rear fog lights on due to heavy snowfall. A vehicle approaches from behind, and as it gets closer, you can clearly see its headlights and it maintains a safe following distance.
Turn off your rear fog lights as soon as you are certain the following driver has sighted your vehicle.
Once the driver behind you can clearly see your car with normal lighting, your rear fog lights become an unnecessary and potentially dazzling distraction. Switching them off prevents blinding or discomforting other road users, which is a legal requirement in Sweden and a fundamental safe driving practice.
Driving in light drizzle during dusk on a well-lit urban street, where visibility is slightly diminished but you can still easily see vehicles several car lengths away, both ahead and behind.
Do not use your rear fog lights; rely on your regular dipped headlights and tail lights.
Rear fog lights are strictly for *severely* reduced visibility, not for general poor weather conditions. In light drizzle, their intense brightness would be unnecessary and could dazzle or confuse other drivers, making it harder for them to judge distances or react to your vehicle safely. Using them inappropriately is against Swedish traffic rules.
Learn about rear fog lights (dimbakljus) in Swedish driving theory. Essential for extreme poor visibility, but must be used correctly to avoid dazzling other drivers. Key for road safety and theory test success.
Rear fog lights, known as dimbakljus in Swedish, are specialized, high-intensity red lights located at the rear of your vehicle. Their primary function is to significantly enhance the visibility of your car to following traffic during conditions where visibility is severely impaired. This includes situations like dense fog, heavy rain, or intense snowfall. Unlike standard tail lights, rear fog lights emit a much brighter, more concentrated beam, designed to penetrate poor atmospheric conditions and alert other drivers to your presence, thereby reducing the risk of rear-end collisions.
According to Swedish traffic regulations, rear fog lights should only be used when visibility is severely reduced due to specific weather conditions such as fog, heavy precipitation, or other comparable circumstances. This means they are not intended for general bad weather, but rather for extreme situations where normal vehicle lighting is insufficient for other road users to clearly see your vehicle at a safe distance. Using them outside these conditions is not only against the rules but also dangerous.
Crucially, due to their high intensity, rear fog lights can be dazzling to drivers behind you. The Swedish Traffic Ordinance (Trafikförordningen) explicitly states that lights and headlights must not be used in a way that can blind other drivers. Therefore, as soon as visibility improves to a point where following vehicles can clearly see your car with its regular lights, or once you are certain that the driver behind you has sighted your vehicle, you must switch off your rear fog lights. Failing to do so can create glare, impairing the vision of the driver behind and potentially causing a hazard, which is a common point of confusion for new drivers and a frequent topic in the Swedish driving theory exam.
Questions about dimbakljus are common in the Swedish driving theory exam. You'll need to know not only when to switch them on (severely reduced visibility) but also, just as importantly, when to switch them off (when visibility improves or following drivers have sighted you). Examiners often focus on the dazzling effect and the responsibility of the driver to avoid blinding others. Understanding the specific conditions and the 'on-off' dilemma is key to answering these questions correctly and demonstrating a strong grasp of road safety.
It's important not to confuse rear fog lights with other types of vehicle lighting. They are distinct from regular tail lights, which are always on and provide general visibility. They are also different from front fog lights (dimljus), which are positioned at the front of the vehicle and designed to illuminate the road ahead in foggy conditions. While both front and rear fog lights are for poor visibility, the rear ones are exclusively for being seen by traffic approaching from behind, and their usage rules are more stringent regarding their dazzling potential.

Dimbakljus are powerful red lights at the back of your vehicle designed to make you visible in conditions of extremely poor visibility, such as dense fog, heavy snowfall, or torrential rain. They are distinct from regular tail lights due to their much higher intensity, crucial for road safety understanding in Swedish driving theory.
According to Swedish traffic rules, you may only use rear fog lights in severely reduced visibility due to fog, heavy precipitation (like snow or rain), or similar conditions. They are not for general bad weather, but specifically when normal lights are insufficient for other drivers to see you, vital for safe driving practices and theory test preparation.
Rear fog lights are extremely bright and can dazzle or temporarily blind drivers behind you. Once you are certain that following vehicles can see your car clearly with normal lighting, you must switch off the dimbakljus to prevent creating a hazard and to avoid discomfort for other road users, which is a legal requirement for safe driving in Sweden.
No, you should not use rear fog lights in light rain or drizzle. Their use is strictly reserved for conditions of *severely* reduced visibility where normal lights are inadequate. Using them unnecessarily can be dangerous as their glare can confuse other drivers, impacting their judgment of distance and potentially leading to accidents, a key point for road safety understanding.
In Sweden, rear fog lights are not mandatory equipment for all vehicles. However, if a vehicle is equipped with them, there must be a warning light on the dashboard to indicate when they are active. Regardless of whether they are mandatory, understanding their correct usage is critical for the Swedish driving theory exam and overall road safety.
