Know Before You Go

Be Safe - Be Prepared - for Late Spring Driving Conditions

  • Watch for potholes. Winter’s freeze/thaw cycle weather can damage roadways, including the creation of potholes. Spring rain also can make them difficult to see. And they can damage your vehicle, requiring expensive repairs. Keep a safe following distance in case the driver in front of you reacts unpredictably. Avoid swerving if you can to avoid a pothole.
  • Slow down for spring showers. Roads become slick when it first begins to rain because rainwater mixes with road contaminants, like oil and grease. Increase your following distance to allow for proper braking.
  • Watch for pedestrians and bikes. Warmer temperatures mean more people are outside walking or bicycling. Slow down and pay extra attention at crosswalks and along roadways.
  • Share the road with motorcycles. Motorcycles may quickly come in and out of your blind spots due to their speed and size. Always take a second look with more motorcycles out on the road.
  • Animals are on the move. Animal activity increases during the spring, either due to mating season or because they are waking up from winter hibernation. Deer are most active at dawn and dusk.
  • Maintain proper tire air pressure. Tires lose air due to the cold winter temperatures and now can be underinflated. Warmer temperatures can cause tires to be overinflated.
  • Inspect your tires. Adequate tire tread is important for safe driving in wet weather because the tread moves water away from the tire. Less tread means reduced traction.
