Which strategy can help you identify the presence of surveillance along your route?

Changing your route regularly is an effective strategy for identifying the presence of surveillance along your route. This method introduces unpredictability to your travel pattern, making it more difficult for anyone attempting to monitor your movements to establish a routine or anticipate your actions. By varying your routes, you increase the likelihood of detecting unusual or suspicious behavior that may indicate surveillance activities.

Regularly altering your path also prevents potential adversaries from developing a consistent understanding of your patterns, which can help reduce the risk of being tracked or targeted. This strategy keeps you more aware of your surroundings and may prompt you to notice details that would otherwise blend into a familiar routine.

In contrast, the other choices do not inherently contribute to detecting surveillance. Using only main roads may actually make you more predictable, while traveling without a plan can lead to random routes that may inadvertently expose you to greater risk. Sticking to familiar terrain limits your ability to notice abnormal activity as you may not be on alert in a known environment. Thus, changing your route regularly stands out as the most effective approach for identifying surveillance.
