During hot summer months, truckers often sleep in their cabs, so they need to keep the engines running to power the air conditioner. In cold weather, idling helps keep the cab warm.
2. Idling helps to prevent engine problems.
When an engine is turned off, the oil can settle in the oil pan and become thicker. This can make it difficult for the engine to start, and it can also cause damage to the engine. Idling helps to keep the oil circulating and prevents it from becoming too thick.
3. Idling can help to conserve fuel.
When a truck is idling, it uses less fuel than it would if it were driving. This is because the engine is not working as hard when it is idling.
4. Idling helps to reduce noise pollution.
Trucks that are idling produce less noise than trucks that are driving. This is because the engine is running at a lower speed when it is idling.
5. Idling helps to keep the emissions system running properly.
The emissions system on a truck is designed to control the amount of pollutants that are released into the air. When an engine is idling, the emissions system is still running, and this helps to reduce the amount of pollutants that are released.
