Signage on the back of trucks carrying dangerous goods is mandatory, and are a heads up for other road users, and emergency response. They are also mandatory for freight crossing the Cook Strait on the ferries, a vital link for many companies.

However not all signs are equal.

Stronger, more durable

Long-lasting TransQuip signs are built stronger and smarter.

The stainless-steel border won’t rust. That’s important not just for durability and strength but also for a professional look for the business and the driver.

The 17 different pages of the flip signs are thicker aluminium for toughness which means they won’t bend which can result in messages being distorted, and the clips have a tab that curves around to hold them in place so they cannot twist out or off, saving you money replacing signs from damage and wear.

Other flip signs like steel powder coated signs can start to rust away when the protective layer of powder coat starts to chip off after use, like in the photo below.

Powder-coated steel flip signs, like the one below, with corrosion, leach down and leave rust marks, and the clips tend to fall out. This detracts from the clean, tidy truck and trailer bodies and is a tarnish to an otherwise awesome truck and trailer.

Other options

Other signage like a dangerous good sign holder, while being cheaper is inconvenient as you have to store the un-used sign messages in another location, taking up space that could be used for essential tools or even a first aid kit. They also have a greater risk of getting bent as they have to be stored elsewhere and not in place.

Why flip signs?

Flip signs save a lot of time and money.

Different vehicles can be carrying different freight at different times. Flip signs deliver flexibility for couriers and haulage fleets, that meet their day-to-day needs.

Lives may depend on them

Signs indicate whether vehicles that are carrying flammable, explosive, toxic, corrosive and infectious substances, or multiple hazards.

If a vehicle was to roll, or be involved in a collision, for emergency responders (and the people who call-in the incident) the sign makes them aware of the potential dangers

and the possibility of a toxic spill. Or explosion.

Clear messaging is vital in an emergency.

Best foot forward

Flip signs can also help with brand awareness. When a vehicle is not transporting dangerous goods, it is an opportunity to promote the company’s brand, logo, or a positive traffic safety message. In effect it’s a moving billboard, and we can customise our flip signs with your logo!

It’s tough out there

Sign durability is important because trucks, and other delivery vehicles, cover a big distance, often in challenging conditions; rain, wind, gravel flying up from the road, and downdraft.
