Short answer
Three things are required:
1. Exercise extreme caution when operating a commercial motor vehicle in hazardous conditions.
2. Reduce speed when hazardous conditions exist.
3. Discontinue operation of the commercial motor vehicle if conditions become sufficiently dangerous.
The rule says
"Extreme caution in the operation of a commercial motor vehicle shall be exercised when hazardous conditions, such as those caused by snow, ice, sleet, fog, mist, rain, dust, or smoke, adversely affect visibility or traction." (49 CFR 392.14)
"Speed shall be reduced when such conditions exist." (49 CFR 392.14)
"If conditions become sufficiently dangerous, the operation of the commercial motor vehicle shall be discontinued and shall not be resumed until the commercial motor vehicle can be safely operated." (49 CFR 392.14)
In plain English
This rule is about safety in bad weather or other hazardous conditions. It means drivers need to slow down or even stop if the conditions are bad enough. The goal is to avoid accidents and keep people safe. Inspectors will check that drivers are following this rule, especially in areas prone to bad weather.
What to do
- Check the weather forecast before heading out on a trip.
- Reduce speed if visibility or traction is poor.
- Pull over and wait if conditions become too hazardous to continue driving safely.
