Traffic Advisory for September 29 - October 5, 2025

Road Safety Reminder for the Week

Hydroplaning
Hydroplaning occurs when driving in wet or rainy conditions. Hydroplaning is a vehicle riding on water because the tires lose all contact with the road. A slight change of direction, applying the brakes, or a gust of wind could throw the vehicle into a skid.

To avoid hydroplaning:

• Drive slowly.
• Steer around standing water, if possible.
• Slow down if you hear sloshing sounds from the tires.
• Slow down when changing lanes or direction.

If your vehicle starts to hydroplane:

• Slow down gradually
• Do not use the brakes. Sudden braking may cause you to lose control of your vehicle.
