Make sure that drivers know the rules. Use a "truck drivers all dropped trailers must be chocked and secured with safety jacks" sign. Make sure that your truckers are the safest on the road.
• A sign is a necessary and effective way to comply with safety regulations of all kinds.
• A sign makes it clear that you are invested not only in the machines you use, but the people who operate them.
• A sign makes your message easy for everyone to see.
