If an officer needs to establish traffic control, what could they use as a barrier?

Using a police unit as a barrier during traffic control is an effective strategy for ensuring the safety of both officers and the public. The vehicle's size and weight create a significant physical obstruction that can deter traffic from entering a hazardous area. By positioning the police unit at an appropriate angle, officers can create a clear and visible barrier that alerts drivers to the presence of an incident or checkpoint and directs them safely away from danger.

Traffic cones, while useful for marking lanes and delineating areas, do not provide the same level of visibility or protection as a police vehicle. Flares are effective for alerting drivers to the situation, but they lack a physical barrier component and can be hazardous if not managed properly. A citizen volunteer can assist with directing traffic, but they do not provide a robust physical barrier or the same authority and presence that a police unit does. Therefore, using a police vehicle stands as the most substantial and effective option for establishing traffic control.
