A technique for enhancing safety during traffic stops includes which of the following?

Utilizing stealth and cover during traffic stops significantly enhances safety for law enforcement officers. This technique allows officers to approach a situation with a degree of caution and preparedness, reducing their exposure to potential threats. By employing stealth, officers can remain discreet and assess the situation without alarming the driver or drawing unnecessary attention to themselves.

The use of cover is equally crucial as it provides physical protection from potential dangers, such as an unseen assailant or erratic behavior from the stopped vehicle. In scenarios where there may be a heightened level of risk, employing both stealth and cover allows officers to maintain a tactical advantage and make informed decisions based on the behavior of the occupants.

In contrast, while other options may seem beneficial in certain contexts, they do not provide the same level of proactive safety. Waiting for backup is important, but it can delay the engagement with an unstable situation. Approaching with lights off can reduce visibility and create uncertainty about the officer's intentions. Signaling a vehicle to pull over from a distance can provide more time to react, yet it does not address the immediate safety concerns of the officer during the actual approach. Therefore, the most effective technique for enhancing safety during traffic stops is utilizing stealth and cover.
