Since Law 14.071/2020 came into effect in 2021, the use of low beams during the day on single-lane highways has generated doubts and, for many drivers, problems. Although the main goal is to increase safety on the roads, the changes in the headlight law confuse a good portion of the drivers and cause penalties that could be easily avoided. Almost four years after the implementation of the regulation, many still do not master the new rules, resulting in fines and loss of points on the driver’s license.
The law requires the use of low beams on single-lane highways, regardless of location, that is, in both urban areas and rural regions where visibility is critical. On these roads, headlight illumination helps prevent collisions, especially on roads where there is no physical separation between lanes, such as guardrails or central medians. In contrast, on dual-lane highways – those with a clear division between directions, the daytime use of headlights is no longer mandatory.
Specific Requirements:
Single-lane highways: low beams are mandatory during the day.

Dual-lane highways: daytime use of headlights is exempt, as the structure of the lane reduces the risk of collisions.
This change aims to provide additional safety where it is most needed, ensuring that vehicles become visible in sections of roads that present a higher risk of accidents.
Penalties for Non-Compliance with the Changes in the Headlight Law
For drivers who do not comply with the legislation, the cost is quite steep. The infraction is classified as medium and results in a fine of R$ 130.16, in addition to adding four points on the driver’s license. These penalties aim to increase awareness about the importance of visibility on the roads, especially in areas where the risk of accidents is high.
The impact of an infraction goes beyond the monetary value; each point on the license brings the driver closer to suspension of the license, which implies serious disruptions in the daily lives of those who depend on their vehicle.
How Drivers Can Adapt to the Changes in the Headlight Law?
To avoid fines and maintain safer traffic, drivers should prioritize understanding the rules in effect. Measures such as refresher courses and frequent consultations of official traffic channels can be useful to ensure compliance with the legislation.
Recommendations for Drivers:
Constant update: drivers should keep track of changes in the rules and familiarize themselves with best practices.
Refresher courses: ideal for reviewing legislation and understanding how to apply it in daily life.
Consultations to official platforms: information is always updated about the law and its practical application.
Beyond avoiding penalties, compliance with the rules is part of a collective effort to reduce accidents and create a more harmonious environment on the roads.
New Technologies and Alternative Solutions
With the evolution of automotive technology, new alternatives to traditional headlights are being incorporated, such as daytime running lights (DRL). These lights, already present in many modern vehicles, ensure daytime visibility without the need for low beams. Thus, vehicles equipped with DRL are exempt from using low beams on single-lane highways, providing greater convenience and a practical alternative to meet legislation.
The changes in the headlight law have come to increase safety and reduce the risks of accidents on Brazilian roads. For drivers, being well-informed about the specifics of the new rules is essential to avoid unnecessary penalties and, at the same time, contribute to safer traffic. Staying aware of technological innovations in the automotive sector also helps simplify compliance with legislation, ensuring a smoother experience on the roads.
