Wind Speed Driving Guidelines

0-25 mph Safe to Travel
Normal driving conditions. Maintain regular speed.
25-35 mph Drive with Caution
Reduce speed by 10-15 mph. Firm grip on steering wheel. Expect buffeting from crosswinds.
35-45 mph High Risk
Strongly consider stopping. If must drive, reduce speed to 40-45 mph max. Avoid passing.
45+ mph Do Not Travel
Pull over immediately. Seek shelter. Risk of rollover is severe.

High Wind Safety Checklist

Before High Winds

Retract all awnings completely
Bring in or secure all outdoor items
Retract TV antenna and satellite dishes
Close and secure all windows and vents
Check that entry door is properly latched
Deploy stabilizer jacks if parked
Place wheel chocks on both sides
Park perpendicular to wind if possible

While Driving in Wind

Reduce speed and increase following distance
Grip steering wheel firmly with both hands
Anticipate gusts when passing large vehicles
Watch for wind indicators (flags, trees, smoke)
Be extra cautious on bridges and overpasses
Avoid sudden lane changes or sharp turns
If trailer sways, ease off accelerator gradually
Pull over if conditions become unsafe

Understanding Wind Dangers for RVs

Why RVs Are Vulnerable to Wind

RVs have a high center of gravity and large surface area relative to their weight, making them particularly susceptible to wind forces. Unlike passenger vehicles, RVs act like sails, catching wind and creating significant lateral forces. Crosswinds are especially dangerous as they can push the vehicle sideways or even cause rollovers in extreme conditions.

Critical Wind Thresholds

Most RVs can safely handle winds up to 25 mph when driving. Between 25-35 mph requires caution and reduced speeds. Above 35 mph, travel becomes increasingly dangerous, with rollover risk rising significantly. At 45+ mph sustained winds, even parked RVs are at risk, especially with awnings extended or slideouts out.

Wind Direction Matters

Crosswinds (side winds) are 30% more dangerous than head or tail winds due to the larger surface area exposed. Quartering winds (diagonal) create unpredictable forces that can suddenly push the RV off course. Wind direction can change rapidly, especially in mountain passes or open plains.

Common Mistakes

  • • Leaving awnings out in windy conditions (can tear off)
  • • Continuing to drive when winds exceed 35 mph
  • • Not accounting for wind gusts (often 20+ mph higher)
  • • Parking broadside to prevailing winds

Critical Safety Warning

This calculator provides estimates based on typical conditions. Actual wind dangers vary significantly based on specific RV design, loading, tire pressure, and real-time weather patterns. Always err on the side of caution. When in doubt, pull over and wait for conditions to improve. Your safety is worth more than any schedule.
