How can you check the weather forecast before a trip on the highway?

Information to check on your route

Before hitting the road, it’s a good idea to check several details related to your route: travel time, traffic conditions, areas of slow traffic, roadwork, reported accidents, and any detours. For a trip in an electric vehicle, it’s also helpful to locate available charging stations, check their accessibility, and estimate potential stop times, so you can plan your trip with greater peace of mind.

The differences between local weather, weather along the route, and weather at the destination

Local weather describes conditions at the starting point, weather along the route tracks changes encountered along the way, while weather at the destination indicates the expected conditions upon arrival. These three types of information are not interchangeable: a trip may begin under clear skies, pass through an area of rain or wind, and then end in a very different climate. Comparing them allows you to plan breaks, adjust your driving, and better organize your departure.

Hour-by-hour and section-by-section forecasts

Hour-by-hour and section-by-section forecrasts provide a detailed overview of your trip by breaking down each stretch of highway and showing how conditions change throughout the day. This approach helps you identify the best times to set out, anticipate traffic changes, and plan your breaks—especially when you’re planning to stop at a charging station. It allows you to travel with a clear understanding of your route and better manage your time on the road.

Weather alerts and advisories for adverse conditions

In the event of heavy rain, strong winds, snow, or fog, weather alerts and advisories should be checked before and during the trip, as they highlight potential traffic hazards. This information allows you to adjust your speed, plan for longer breaks, and, if necessary, postpone your departure to travel under better conditions.

List of things to do before getting on the highway

• Check traffic conditions, any roadwork, and areas of slow traffic along your route.
• Check your fuel level or electric range before departure.
• Have your payment methods and electronic tolltag ready to speed up the toll process.
• Locate rest areas in advance and, for electric vehicles, available charging stations.
• Make sure the vehicle’s equipment is in good condition: tires, lights, windshield wipers, and phone battery level.

Adjust your departure time based on the forecast

When the forecast calls for rain, fog, strong winds, or snow, it’s often best to postpone your departure until a time when conditions are more stable and there’s better visibility, to reduce risks and drive with greater clarity. Adjusting your departure time also helps you avoid periods of heavy traffic, better manage breaks, and—for electric vehicle trips—recharge under optimal conditions.

Prepare your vehicle and equipment for the season

Seasonal vehicle preparation improves safety and comfort on the highway, whether it involves switching to appropriate tires, checking the battery, windshield wipers, or fluid levels. In winter, items such as an ice scraper, gloves, and a blanket can come in handy, while in summer, it’s a good idea to check the air conditioning and bring water along.

Information Signs and Traffic Messages on the Highway

On the highway, information signs and traffic messages provide real-time updates on traffic delays, accidents, roadwork, or adverse weather conditions. Installed above the lanes, they help drivers adjust their driving, choose a route with smoother traffic flow, and better plan for a break.

Weather Updates During Rapid Changes

When the weather changes suddenly, it’s essential to check real-time updates to anticipate sudden rain, gusts of wind, icy conditions, or reduced visibility on the highway. This information allows you to adjust your speed, reschedule a break or refueling stop, and ensure a safer, smoother trip.

Best Practices for Reduced Visibility or Severe Weather

In the event of fog, heavy rain, snow, or strong winds, it’s essential to reduce your speed, increase your following distance, and turn on the appropriate lights to remain visible. You should also avoid sudden maneuvers, pay constant attention to traffic signs, and plan a break if conditions become too difficult.
