Section 4: Sign Height

Introduction

The proper sign height:

Improves the visibility of the sign, and

Provides appropriate safety performance.

Signs that are too low may not be visible to road users, particularly in heavy traffic. Likewise, signs that are too low may intrude into the vehicle compartment when struck.
