During the months of September and October, increased rainfall due to indirect effects of hurricanes and other weather phenomena has prompted authorities to call for greater caution on the roads, especially concerning cyclists.
According to Martín Sánchez Agüero, deputy director of the Traffic Police, darker, cloudy, foggy, and rainy days create higher risks for all road users. Cyclists and pedestrians are particularly vulnerable because they face more severe consequences in the event of a collision with motor vehicles.
Sánchez explained that both cyclists and pedestrians need to make themselves more visible on the road. “Luces en la bicicleta, en el casco y en un chaleco o en la ropa en sí, son buenas ideas para los ‘cleteros’, mientras que usar ropa clara o reflectante de la luz es recomendable para los peatones,” said Sánchez. He also issued a general warning: “Asimismo, el funcionario quiso enviar esa voz de alerta a todos los actores viales, en general, sean conductores, motociclistas, peatones y ciclistas, para que asuman conductas más prudentes en carretera.”
Key recommendations for drivers include reducing speed and maintaining greater distance between vehicles. These suggestions also apply to cyclists. Visibility is crucial for all vehicles; turning on headlights not only helps drivers see but also ensures they are seen by others. “Se debe comprender que, aunque se pueda ver el camino sin las luces encendidas, las luces también son para ser visibles ante los demás,” Sánchez emphasized.
Cyclists and motorcyclists are advised to be cautious around manhole covers and railway lines when wet because these surfaces can be slippery. It is recommended to avoid them or cross at low speeds.
Following traffic rules—such as not driving against traffic flow, obeying signals and signs—is essential for risk reduction. Cyclists should also avoid overtaking on the right side.
Wearing reflective clothing is advised for visibility. In cases of very adverse weather conditions typical of this season, stopping may be considered as an additional safety measure.
Authorities have also called on drivers to show empathy toward cyclists. Drivers are urged to pay closer attention so they can better spot cyclists on the road and respect a minimum passing distance of 1.5 meters when overtaking them.
Giving way to cyclists or even escorting them during foggy or rainy conditions—especially in rural areas or winding roads—is encouraged as a supportive gesture.
Drivers are asked not to pressure cyclists into moving aside or speeding up.
As of July 2025, there have been 22 cyclist fatalities reported on Costa Rican roads—a rise compared to 18 deaths recorded by July 2024—highlighting an increase in cyclist fatalities over the past year.
