Why Parking Lot Sign Posts Matter More Than You Think

Nearly 1 in 5 traffic accidents happen in parking lots. Most are preventable. Both drivers and pedestrians spend as much time in parking areas as they do on the open road, if not more. For this reason, it’s important for everyone to remember the fundamentals of parking lot safety, as well as encouraging awareness through the use of strategically placed parking lot sign posts.

A Lack of Awareness

Drivers failing to see other vehicles or pedestrians when backing up. Tragically, children are often the victims in these incidents, due to their small size and impulsive nature. These kinds of accidents are especially common when the moving vehicle is surrounded by parked automobiles that limit the driver’s range of vision.
Pedestrians who move between parking spaces instead of following established walkways. This bad habit blocks escape routes from an inattentive driver or out-of-control vehicle.
Petty competition between drivers over getting the “best” spot. This is especially a problem during the holiday season, when busy consumers are focused more on shopping than on safe driving.
Poorly maintained parking areas that lack lighting and signage or contain crumbling asphalt and potholes. These problems compromise visibility and create safety hazards for both motorists and pedestrians.
Nighttime or periods of inclement weather that make it difficult for parking lot users to see what’s going on around them. This is perhaps the most common challenge to parking lot traffic control.

Fortunately, it’s possible to prevent most parking lot traffic control mishaps simply by improving alertness and awareness. Both drivers and pedestrians should look around them constantly when traveling through parking areas. They should avoid using cell phones or other mobile devices that cause distractions, and focus more on ensuring everyone’s safety than on getting to their destination quickly. These principles, alongside adequate parking lot sign posts, can help prevent most parking lot traffic control accidents.

Improving Parking Lot Sign Posts Visibility

Parking lot sign posts serve a vital purpose: they convey important information and help to prevent accidents and injury. However, they can only perform these functions when easily visible. Fortunately, psychologists have conducted studies and determined common factors that aid visibility. These include:

1. Proper height.

Effective sign posts should be high enough for drivers to easily see. Generally, 5 feet from the surrounding surface to the bottom of the sign is considered sufficient for these purposes. In some cases, parking lot sign posts are located 7 feet or higher, such as when they designate specific zones in the lot.

2. Proper coloring.

Studies show that the human eye most readily perceives messages in a tone that strongly contrast with the background color. Yellow and black are common combinations, as are red and white.

3. Proper construction.

Parking lot sign posts must be able to withstand low-speed impact with vehicles without suffering significant damage. There are two ways to achieve this purpose. One is to construct the sign posts from steel or another resilient material. Another is to mount it on a spring-loaded base. One method relies on resisting the force of impact, the other on the “bend rather than break” principle.

4. Proper communication.

Drivers have minimal time in which to interpret signage. A delay of even a few seconds can cause accidents and injuries. For this reason, parking lot sign posts must contain simple, direct messages that are easy to understand. Clear, short text and universally used graphics help to achieve this purpose.

5. Proper placement.

Even the most carefully designed parking lot sign posts are useless unless they’re located where drivers and others can easily see and respond to them. In general, installers should place signage in front of each space as well as at entry and exit points.

Parking lot sign posts are among the most useful public safety devices available. To accomplish their purpose, however, they must be used according to best practices and installed correctly.
