You See Police in the Car Behind You. Your Move Matters.

You’re driving, maybe running errands, maybe on your way home. You glance in the mirror—and there it is: a police car behind you.

Even if you’ve done nothing wrong, the anxiety kicks in.

And if they turn those lights on? What you do next could have serious legal consequences.

This guide explains exactly what to do when you’re stopped by police in Canada, how to avoid making the situation worse, and what rights you do (and don’t) have.

First: Are You Being Pulled Over?

If the police in the car behind you have flashing lights or sirens, you’re legally required to pull over immediately. Failing to do so can result in:

  • Failing to stop for police

  • Obstruction

  • Even flight from police—a criminal charge

How to pull over safely:

  • Signal right

  • Slow down calmly

  • Stop in a safe, well-lit area

  • Turn off your ignition

  • Roll your window down slightly

  • Keep your hands visible on the steering wheel

What Do You Have to Show Police?

At a traffic stop, you’re legally required to provide:

  • Driver’s licence

  • Vehicle registration

  • Proof of insurance

That’s it.

You are not required to answer questions like:

  • “Where are you coming from?”

  • “Where are you going?”

  • “Have you been drinking?”

You have the right to remain silent. It’s smart to use it—especially if you’re being investigated for a criminal offence.

Can Police in the Car Search Yours?

Police can only search your vehicle under specific circumstances:

  • You’ve been arrested and they believe the vehicle contains evidence

  • They have a search warrant

  • There’s an urgent public safety concern

  • They see something illegal in plain view

You can say:
“I do not consent to a search.”

Even if they search anyway, this statement may help your lawyer challenge the evidence in court.

DUI Checkpoint? Know This First.

Under Canadian law, police can now demand a breathalyzer test even without smelling alcohol or observing erratic driving. If you refuse, you can be charged with refusal to comply—a criminal offence.

However, you still have the right to:

  • Remain silent

  • Ask to speak to a lawyer immediately if you’re arrested

Related: What If You’re Charged After the Stop?

If you’re arrested after being pulled over:

  • You have the right to be told why

  • You have the right to speak to a lawyer without delay

  • You have the right to remain silent

Resisting arrest—even if you believe it’s unfair—can result in additional charges like obstruction or assaulting a peace officer.

Once safe and released, contact a defence lawyer as soon as possible.

Why You Should Call a Lawyer—Even If It’s “Just a Traffic Stop”

We’ve helped many clients who were stopped for minor infractions—like a broken tail light or tinted windows—only to face far more serious charges.

A lawyer can:

  • Challenge illegal searches or detentions

  • Ensure your Charter rights were respected

  • Negotiate for dropped or reduced charges

  • Represent you at court appearances or bail hearings

Final Thoughts: Police in the Car Isn’t Always the Problem—Your Response Is

Most roadside stops don’t turn into criminal cases. But when they do, it’s often because the driver:

  • Said too much

  • Gave consent without realizing it

  • Got angry or confrontational

  • Didn’t call a lawyer soon enough

Don’t let that be your story.
