With the arrival of rain, the asphalt becomes more slippery and driving requires greater attention. Many drivers adjust their speed, but they make a recurring mistake that can be costly: using the car’s lights incorrectly. According to the Automóvel Club de Portugal (ACP), carelessness at this point can generate fines of up to 600 euros.
Mandatory dipped beam lights
It is common to see vehicles driving with just their side lights or daytime running lights during the rain. The Highway Code, however, is clear: in situations of reduced visibility, such as heavy rain, fog or snow, it is mandatory to turn on the dipped beam.
Driving only with the minimum is an infraction punishable by a fine of between 60 and 300 euros, depending on the severity.
Fog lights: correct use
Rear fog lights should only be used when visibility is very low. Its improper use causes other drivers to become blind and is considered a very serious offense, with fines that can reach 600 euros.
The rule of thumb is simple: whenever the windscreen wipers are on, the dipped beam should also be on. This improves visibility and makes the vehicle easier to detect, reducing the risk of accidents.
Risk of hydroplaning
Rain increases the risk of aquaplaning, when the tires lose contact with the asphalt and the car slides over the water. At these times, control of the vehicle is temporarily lost.
Tire maintenance is essential. Portuguese law requires a minimum depth of 1.6 mm, but experts recommend changing tires when the grooves reach 3 mm. A small but crucial difference on wet floors.
If aquaplaning occurs, the driver must remain calm: ease off the accelerator, hold the steering wheel firmly and let the car regain grip. Sudden braking or sudden movements increase the danger.
Speed and safe distance
Rain prolongs the braking distance, making it necessary to reduce speed and increase space for the vehicle in front. The recommendation is to reduce the permitted limit by approximately 20% and double the safety distance. For example, if on dry ground two seconds are enough, on wet ground it should be four.
Avoiding risky overtaking, quick turns and sudden braking are essential measures. Driving in the rain requires attention, caution, correct maintenance and compliance with safety rules.
According to , ensuring good visibility and always driving with headlights on is the first step to avoiding accidents and fines. A simple gesture can make all the difference between a smooth trip and a high bill.
