This creates critical situations, especially on rural roads, which are often underestimated. The danger increases particularly on hilltops, at the end of bends, on east-west roads, and when leaving towns, tunnels, or wooded areas. Wet roads increase the risk as they reflect sunlight and further impair visibility.

Alarming figures: accident statistics on sun glare

According to official statistics, there were 2,529 accidents with personal injury in Germany in 2023 that were attributed to glare from the low sun. A total of 3,274 people were injured, including 529 seriously and 31 fatally. In Austria, 24 deaths and over 2,000 injuries were recorded during the same period. These figures illustrate how serious the danger is.

Recognizing the most important warning signs early on

Experienced motorcyclists recognize glare hazards early on based on typical indicators:

1. Shadow in front of the motorcycle: If your own shadow is clearly visible in front of the front wheel, you should exercise particular caution. Reduce your speed and be ready to brake.
2. Reflective road surface: Bright reflections on wet or dusty roads are warning signs. The area behind such a reflection is often invisible.
3. Junctions and sightlines: Side streets behind bushes, buildings, or trees are critical points. Slightly shifting your line within your own lane can help you to be seen earlier.

Small movements, such as lane deviation, increase visibility to other road users, as the human eye recognizes movement faster than a stationary point. At the same time, a lateral distance increases your own reaction zone in the event of vehicles suddenly turning in.

Driving line, speed, visibility: tactics against glare traps

As soon as shadows appear in front of the motorcycle, it is important to drive with foresight. Adjust your speed so that you can stop safely at any time within the visible distance. A slight lane deviation within your own lane improves your line of sight and reduces the risk of driving in the glare axis.

Always be prepared to brake: keep two fingers on the brake, change loads gently, and avoid abrupt steering maneuvers. Slowing down gives you more time to react – this is the best protection in dangerous situations.

Increase visibility: lights, headlight flashers, and legal requirements

In Germany, traffic regulations require drivers to use lights even during the day – either low beams or daytime running lights. High beams are prohibited on sufficiently lit roads and may only be used if they do not dazzle other drivers. When there is oncoming traffic, you must dip your headlights in good time.

Your headlights may be used to warn of dangerous situations. However, they are not a means of enforcing right of way. Similar regulations apply in Austria and Switzerland: lights must be on around the clock, and daytime running lights or low beams are mandatory. The aim everywhere is to improve the visibility of single-track vehicles.

Driving with high beams during the day is generally permitted as long as no one is dazzled and there is no continuous street lighting. As soon as an oncoming vehicle becomes visible, you must switch to low beams.

Practical tips for greater safety when the sun is low

• Incorporate small movements: Subtle lane changes within your own lane draw attention to the motorcycle.

• Use your headlights sensibly: Warn briefly in case of danger, but do not flash continuously.

• Adjust your speed: Driving slower gives you more time to react.

• Make eye contact, but don’t rely on it: A brief glance does not mean that the other person has actually noticed the motorcycle.

• Recognize critical areas: Hilltops, tunnel exits, junctions in the direction of the sun, reflective roads, and shaded areas are particularly dangerous.

• Open up your line of sight: Gain as much visibility as possible by shifting lanes so that you are noticed earlier.

• Have an emergency plan ready: Constant scans of your surroundings enable you to quickly identify the best evasive route in an emergency. In an emergency, swerve into an open area or field; do not fix your gaze on the obstacle.

   

  
  Legal information and recommendations

  The German Road Traffic Regulations (StVO) stipulate that lights must be used during the day. High beams may only be used if they do not dazzle anyone. The headlight flasher is a warning signal and not a means of communication. If you are unsure, it is better to drive more carefully and, if in doubt, stop until visibility is sufficient again.

   

  
  Conclusion: attentiveness and preparation as life insurance

  Glare from the low sun is one of the most dangerous situations on country roads. Recognizing the signs, adjusting your speed and driving line, and paying attention to visibility significantly reduces the risk of accidents. Attentiveness, anticipatory driving, and good preparation are the best protection—technology such as lights helps, but it does not replace your own risk awareness.
