What is the correct speed to move forward after pushing the tractor valve back in?

Moving forward after pushing the tractor valve back in should be done at a controlled speed to ensure safety and proper functioning of the vehicle. A speed of 5 mph is appropriate because it allows the driver to maintain control and react to any immediate situations that may arise, such as monitoring for any unusual sounds or behaviors from the trailer or the administration of air pressure.

Driving at a higher speed, such as 10 or 15 mph, could lead to a lapse in control in case something is amiss after activating the tractor valve. At lower speeds, like 3 mph, responses might not be timely enough, as the vehicle could still potentially exhibit serious issues. Therefore, 5 mph strikes the right balance between caution and mobility, making it the recommended speed for this scenario.
