Daytime running lights are too bright at night

The law prohibits daytime running lights at night

Some vehicles’ daytime running lights do not turn on the tail lamps, making it dangerous to drive at night

Your score is

This section covers when to use low and high beams, the importance of turning on headlights in poor visibility, such as rain, fog, or dusk, and legal requirements for headlight operation. Drivers are also tested on how to avoid blinding other motorists by dimming high beams when approaching or following another vehicle. Mastery of these rules ensures optimal visibility and safety for everyone on the road. Proper use of headlights is essential for both day and night driving in Saskatchewan.

To enhance your understanding, it is beneficial to engage in the SGI practice test study questions until you are able to articulate the concepts clearly without needing to refer to your notes. This method will strengthen your grasp of the material and improve retention.
