Vibralines are unbroken white lines with bumps usually found at the expressway exits. They are designed as a warning system to help alert drivers to stay to the main course of the road.

If you veer off the road and onto the vibralines, they will make your car shudder and shake. They will also cause the tyres to make a loud whirring noise.

Next time if you experience such vibrations or noise, be alert and stay to the main course of the road!
