What conditions can be considered “severe?”
If you regularly drive in these conditions, your vehicle is being driven in what can be considered severe conditions. Regularly driving in stop-and-go traffic is hard on your vehicle, as well as driving in the extreme heat or cold. Driving with a fully loaded car or towing a trailer or boat can also cause wear on your vehicle. Frequent and/or short commutes like driving to your workplace everyday can be considered severe, and driving in mountains or hills can also fall under this category. Dusty, muddy, graveled or salted roads also cause wear and tear.

Severe Duty Explained
Broadly speaking, automakers define severe duty as operating conditions that regularly put an unusually high amount of strain on a vehicle. GMC cites driving primarily in dense, low-speed urban traffic in hot weather, routinely driving through hilly or mountainous terrain, and regularly towing a trailer as examples of severe duty. Vehicles often driven at high speeds or used for commercial purposes, such as patrol cars, taxis, and delivery trucks, also experience severe duty conditions.
Vehicles primarily used for short trips or in dusty conditions are also subjected to severe conditions

The wording and mileage ranges will vary slightly from one automaker to the next, but in general, these are the criteria for what constitutes “normal” driving conditions:
- Vehicle is driven approximately 12,000 to 15,000 miles per year
- Vehicle is used for an even blend of local and highway driving
- Minimal hills – It’s assumed that the vehicle will be driven on mostly flat or near-flat roads.
- Vehicle is primarily driven in a mild climate with average weather patterns
As you can see, it’s a fairly short list and the conditions probably don’t sound realistic to most reading this.
Everything else is considered “severe”, but for the sake of this discussion, here are the most common “severe” driving situations:
- Vehicle is frequently idled for long periods
- Vehicle is subjected to stop-and-go driving – whether in the city or highway traffic
- Vehicle is driven long distances on the highway in hot temperatures
- Vehicle is used for long-distance trips at speeds that don’t go over 50mph
- Vehicle is frequently started in freezing temperatures
- Vehicle is frequently used for short trips in any temperature, including normal
- Vehicle is driven over rough terrain that includes steep hills or mountains
- Driving on any road that isn’t clean pavement (dusty, dirty, muddy, salted, or gravel roads)
- Vehicle is used for any kind of towing
- Any trip that adds excessive weight to the vehicle through the use of roof rack or car-top carrier
