CAAS GVS 4.0: Building safer, smarter and theft-proof ambulances

EMS veteran Mark Postma joins Rob Lawrence to unpack the latest vehicle standards and share why ambulance security can’t be an afterthought

In this episode of the EMS One-Stop podcast, host Rob Lawrence climbs back onto his soapbox to discuss two topics that directly impact on every EMS agency in America — the CAAS Ground Vehicle Standards (GVS) 4.0 and the simple, inexpensive steps we can take to stop ambulance theft.

Joining Rob is longtime EMS leader and current CAAS GVS Administrator Mark Postma, who walks us through the origins of the standards, their national adoption and what’s new in the latest update.

From ambulance remounting, to structural safety testing, Mark explains how GVS 4.0 has evolved to keep pace with manufacturing realities, supply chain delays and operational needs. The conversation then shifts to a shared passion for protecting fleet assets.

Rob and Mark dissect the shockingly frequent problem of ambulance theft and how a $200 automatic immobilization device can prevent a $250,000 vehicle from disappearing — without relying on crews to remember to lock it.
