What does the barricade angle of 45 degrees indicate?

The barricade angle of 45 degrees primarily indicates the direction that traffic is required to pass. In roadwork and construction scenarios, barricades are employed to redirect vehicles safely and effectively. A 45-degree angle helps to direct drivers' attention towards the appropriate path they should follow around an obstruction, ensuring not only safety but also the smooth flow of traffic.

While the barricade may suggest the general context of the area, such as levels of danger or the nature of the work being performed, the specific angle itself is primarily a visual cue for traffic navigation. This angle helps maintain safety standards on roads by enabling drivers to recognize the intended direction for movement, thereby reducing the risk of accidents or confusion in construction zones.
