June 21, 2024


Quebra Molas, also known as speed bumps, are traffic calming devices used to slow down vehicles in residential areas, school zones, and other areas where speed control is necessary. These raised sections of pavement are designed to force drivers to reduce their speed, improving safety for pedestrians and other road users.

What is Quebra Molas?

Quebra Molas are typically made of rubber, asphalt, or concrete and are placed strategically along roadways to reduce speeding and prevent accidents. They are often painted with bright colors or reflective materials to increase visibility, especially at night or in low-light conditions.

How do Quebra Molas work?

When a vehicle drives over a Quebra Molas, the raised surface causes the vehicle to slow down by creating a jarring effect. This sudden change in speed can be uncomfortable for drivers and passengers, but it serves as an effective deterrent to speeding.
