Last year our district manager enacted a "Clean cab" policy. There were to be no radios or anything loose in the cabs even though most radios were hard wired. Was that company wide or just pipe dream locally? I guess my issue with this is watching the RVM vibrate and rattle around with every bump or rough road. The fire extinguisher that is mounted by a small metal strap. And everything else that is "loosely" mounted by UPS that is in the cab. The reasoning behind this is if the driver was every in wreck then they wanted to reduce the potential projectiles in the cab area.
