How should work zone signage be installed to ensure maximum visibility?

The correct answer emphasizes the importance of installing work zone signage at heights and angles that ensure maximum visibility for approaching drivers. This is critical to ensure that motorists can see warning signs, directional signs, and other relevant information well in advance, allowing them to react appropriately and safely navigate the work zone. Proper visibility is vital for reducing the risk of accidents and keeping both road workers and drivers safe.

Installation at an optimal height ensures that signage is easily seen over obstacles like vehicles or other elements on the side of the road. Furthermore, the correct angle can help draw attention to the signage, making it clearer and more noticeable, especially during various lighting conditions or weather situations. This strategic placement is a fundamental principle in traffic control devices, particularly in dynamic environments such as work zones, where conditions can change frequently.

In contrast, signage placed only at the roadside may not adequately capture the attention of drivers who may be distracted or focused on the road ahead, while signs set back from the road without consideration for angles may become invisible or misinterpreted. Additionally, waiting until the last step of the setup process to install signage could lead to unsafe conditions, as drivers need ample warning before encountering a work zone.
