Divided Highway Ahead Sign

Introduction

As road conditions change, it’s important that drivers are given clear guidance to adjust accordingly. One such situation is the transition from an undivided to a divided highway, where traffic in opposite directions is separated by a median or barrier. The Divided Highway Ahead sign plays a vital role in alerting drivers to this change, and it’s a key concept in the Ontario G1 driving test.

What Does the Divided Highway Ahead Sign Mean?

The Divided Highway Ahead sign is a yellow diamond-shaped warning sign with:

• A black symbol showing two arrows—one curving right and the other left

• A black vertical shape representing a median or divider between the arrows

This sign warns that the road will soon split into two separate lanes, divided by a physical median, and that each direction of traffic will be separated.

Where Are Divided Highway Ahead Signs Typically Placed?

You’ll typically find this sign:

• Before the start of a divided highway segment

• At the entry point of major highway routes

• On rural roads transitioning into multi-lane highways

• Near overpasses or expressway ramps

• In areas with high-speed traffic and safety dividers

Placement follows guidelines from the Ontario Traffic Manual (OTM) Book 6 to ensure drivers have adequate time to adjust.

How Should Drivers Respond to the Divided Highway Ahead Sign?

When you see this sign, you should:

• Stay in your lane and prepare to follow the direction of your respective arrow

• Be aware that oncoming traffic will now be physically separated

• Watch for lane markers, merge lanes, and changes in speed limits

• Avoid trying to cross the median or divider

Ignoring this warning can lead to:

• Improper lane usage or illegal U-turns

• Confusion during merging or exiting

• Increased risk of head-on collisions at unmarked transition points
