Where are the shutoff valves typically located?

The shutoff valves are typically located at the back of the truck and at the end of each trailer to ensure safety and ease of access in the case of an emergency or maintenance situation. This positioning allows drivers and technicians to quickly shut off the flow of air or fluid in various systems, such as the braking system or hydraulic lines, when necessary. The location is strategically chosen to facilitate quick action, especially in scenarios where a malfunction or hazard is detected while on the road.

Other locations, such as under the truck cab or inside the engine compartment, do not provide the same level of accessibility needed in urgent situations. Similarly, having shutoff valves on the dashboard would be impractical and could pose additional safety risks, as accessing them would require taking the driver's attention away from the road. Therefore, the design ensures that the shutoff valves can be reached swiftly without obstructing the driver's view or requiring excessive maneuvering around the vehicle.
