How can you tell if you are being followed?

Two things are true at once: most people who think they are being followed are not, and some people who are followed dismiss it for months. The way to hold both is to stop trying to decide in the moment and start recording data points, because following is established by pattern rather than by any single observation.

What does a real pattern look like?

• The same vehicle or person on different days, not just for a long stretch of one journey
• Presence in unrelated locations — near home, near work, at a shop you rarely visit
• Appearance timed to your departures rather than to traffic
• A vehicle that hangs back, matches your speed changes, or parks where it can see an exit
• Rotation — different vehicles, same pattern. This is what professional surveillance looks like and it defeats plate-spotting entirely
• Someone who looks away or leaves promptly when noticed, repeatedly

What is usually coincidence?

A car behind you through several turns on a main route, especially near a motorway junction or in a corridor where most traffic is going to the same few places. People commute on similar schedules along similar roads. A single journey almost never establishes anything, which is why the useful question is not 'is this car following me' but 'have I seen this before, somewhere unconnected'.

How do you check safely?

The classic route-variation checks work, but safety comes first. Take a route that no reasonable person would coincidentally share — four turns around a block, or a deliberate detour. In a parking lot, note whether a vehicle waits rather than parking. On foot, stop somewhere with a clear view behind you, such as a shop window or a café.

Do not drive home to test it. Do not speed, run lights, or take an unlit route to shake someone. Do not confront, approach, photograph at close range or attempt to follow them. If you are genuinely concerned, drive to a police station, a fire station or somewhere busy and well lit, and call from there.

What should you write down?

Immediately afterwards, while it is precise: vehicle make, model, color and any distinguishing feature; the plate if you can note it safely; the date, time and location; the direction of travel; a description of the occupant; and what you were doing at the time. Even partial details build a pattern when repeated, and 'a dark sedan, twice this week, near the school' is far more useful than a vague recollection weeks later.

Could it be lawful surveillance?

Possibly. Surveillance conducted from public vantage points by a licensed investigator is lawful, and it happens in divorce, custody, insurance and civil matters. If you are involved in any of those, it is a realistic explanation. An investigator who is working will not confirm it if asked — they owe that duty to their client, not to you — so an approach produces nothing except telling them they were noticed.

This does not make it harmless to ignore. Lawful surveillance and unlawful stalking look identical from the inside, and the documentation you keep is useful either way.

When should you involve police, and when an investigator?

Police, if you feel threatened, if there is any contact, or if the pattern continues — even where you are unsure, because a report creates a dated record. An investigator is useful when you need the pattern documented rather than merely reported: identifying a vehicle, establishing whether the presence is genuinely repeated, and producing a record that supports an order of protection. That documentation is usually what converts a sincere account into something a court will act on.
