Turn Signals as a Legal Requirement, Not Just a Courtesy
Last reviewed: 2026 · Driviology Road Safety Education Team
Quick Answer
Turn signals are a legal requirement under Ontario’s Highway Traffic Act, not just a courtesy, and pedestrians and cyclists rely on them just as much as other drivers do to understand a vehicle’s intended path.
This page focuses on turn signals as a legal and communication requirement; our guide to using direction indicators correctly covers the mechanical timing.
A Legal Requirement, Not Just Courtesy
Failing to use turn signals can result in fines and penalties under Ontario’s Highway Traffic Act, making it a legal obligation rather than an optional nicety.
Who Relies on Turn Signals
Pedestrians and cyclists, not just other drivers, rely on turn signals to understand a vehicle’s intended path before stepping into or crossing its way.
A Real-World Scenario
Changing lanes in heavy highway traffic without signalling can force another driver to brake suddenly, a collision risk easily avoided with a signal used in advance.
