Are plastic car ramps safe, or should I buy steel?

Verified-purchase reviewers across the plastic ramps here report them holding typical passenger vehicles fine, and plastic has the advantage of being light and rust-free. That said, plastic ramps can flex, slide on smooth garage floors, and crack if abused or stored in extreme cold. For frequent heavy use or heavier trucks, a metal ramp is the more reassuring choice; always chock the rear wheels and never rely solely on ramps when working under a vehicle.
