No, the DGT does not prohibit specific sunglasses, although improper use can end in a fine

You may have read that the DGT prohibits driving with filter 4 sunglasses (UV), but it is not like that: it is a mere recommendation. i.e. traffic recommends or discourages a certain typewhich due to their characteristics, are more suitable for driving or not.

Likewise, the DGT, in general, recommends wearing sunglasses when we get behind the wheel of a car or vehicle, since this accessory helps to neutralizes glare and the dreaded “temporary blindness”, as well as minimizing visual fatigue.

Especially in the twilight hours, at dawn or dusk, which are the most likely to cause glare due to how the sun’s rays affect the windshield, the rear window or the mirrors.

Be that as it may, and although traffic signals how they should be the most suitable for driving, it is always a recommendation. Of course, not using sunglasses correctly, or using non-recommended ones, can be subject to a fine…

The most recommended glasses for driving, according to the DGT

Sunglasses with brown lens

As detailed by the DGTlas most suitable sunglassess to drive are those that meet these characteristics:

Polarized. These types of glasses have base lenses to which a sheet is added that filters the sun’s rays that fall in a certain direction. In other words, they eliminate reflections and more effectively neutralize glare.

In addition, they better combat eye fatigue and provide greater sharpness and contrast. These types of glasses usually include the letter “P” either inside or outside the rod, or on the lenses themselves.

Lens colour. The ideal and recommended by the DGT are those that have lenses green, gray or brown. Of these, the most advisable are those with brown lenses, since they reduce visual fatigue, do not alter the perception of colors and adapt more effectively to light/shadow areas.

Solar filter. As for the most suitable filter, Traffic recommends those with sunscreen 3, which absorb between 81 and 91% of UV (ultraviolet) rays. On the contrary, It is preferable that are not sunscreen 4 (up to 92% UV), as they are darker and suitable for other activities such as skiing or sailing.

Approved. Lastly, sunglasses must be approved and have suitable lenses so as not to damage your eyesight. That is why it is best to buy them either at opticians or authorized stores. These glasses always have a UV filter and on the rod they show the European Conformity approval (CE)which certifies the quality of the lens material.

5% of traffic accidents are caused by glare at dawn or dusk, despite this 20% of drivers never use this accessory at the wheel.

Can I be fined for not wearing sunglasses correctly or for wearing the wrong ones?


At first, no. Firstly, because the DGT does not expressly prohibit any type of sunglasses, simply does not recommend the use of filter 4 or non-homologated or with crystals that neutralize glare less effectively.

In addition, if we go to the regulations, in the General Regulations for Drivers no requirement is made regarding sunglasses: it simply refers to prescription glasses, necessary for those drivers with visual deficiencies (myopia, hyperopia, astigmatism…).

Now for example the Traffic Regulationsin his article Article 18.1specifies that:

The driver of a vehicle is required to maintain their own freedom of movement, the required field of vision and permanent attention to driving, which guarantees their own safety, that of the rest of the occupants of the vehicle and that of other road users.

Thus, in some situations using sunglasses incorrectly, or ones that are not recommended, could be subject to fine If we get caught up in a incident or accident and a agent interprets that it is direct cause of it, as is the case with driving with flip flops o bulky garments.

For example, in a tunnel, in dark areas or at nightcases in which the DGT itself categorically discourages wear sunglasses, as they ultimately reduce vision in these low-light scenarios. And it also does the same with filter 4, with excessive protection and that can affect the correct vision at the wheel.

Be that as it may, the agent must detail the facts in the complaint. This is a minor infraction and a penalty of 80 eurosor 40 euros if we stick to prompt payment (pay the penalty within 20 days of notification).
