Group Ride Through a Construction Zone
You are leading a group of five motorcycles through an active construction zone on a four-lane urban street. It is 2 p.m. and dry. The right lane is closed by a line of orange drums and a sign showing a lane-closure arrow pointing left. The left lane is open but narrowed to about 3 m by concrete barriers. A flagger in a high-visibility vest is standing near the drums. The speed limit through the zone is posted at 40 km/h, down from 60 km/h. Your group is bunched tightly, with the second rider about 8 m behind you. A dump truck is exiting the site ahead, crossing the open lane toward a gate on the left. The flagger is looking down at a clipboard, not at traffic.
1. Which signs and markings govern this zone, and what do they require of you?

The orange drums and lane-closure arrow sign are temporary traffic-control devices. The arrow pointing left means the right lane is closed and traffic must merge left. You must move into the open lane before reaching the drums - not weave between them.
The posted 40 km/h limit is a regulatory speed limit for the work zone and replaces the 60 km/h limit. It is not a suggestion; it applies until a sign ends it.
The concrete barriers define the narrowed lane. With only about 3 m of width, there is no room for two motorcycles side by side, so the group must ride single file.
The flagger is a traffic-control person. Even though this one is looking at a clipboard, their presence signals that workers or equipment may enter the lane. Treat their position as a warning to slow further and be ready to stop.
2. The flagger is not watching traffic and a dump truck is crossing the open lane. What is your plan for the next few seconds?
Read the worked answer
Slow well below 40 km/h and prepare to stop. The flagger is not controlling traffic, so you cannot rely on them to wave you through or hold the truck. The dump truck crossing your lane is the immediate hazard - it is large, slow, and may not see a motorcycle in a narrowed lane.
- Do not assume the truck will stop. Make eye contact with the driver if possible; if you cannot, assume they have not seen you.
- Increase your following distance from the rider ahead so you have room to stop without the rider behind running into you.
- Signal your intentions early so the four riders behind you know you are slowing.
- Be ready to stop completely before the truck's path, and only proceed when the truck has cleared the lane and you can see the open lane ahead.
3. Your group is bunched with the second rider 8 m back. How should you manage the group through the zone?
Read the worked answer
Eight metres at 40 km/h is too close - you cover about 11 m per second, so the second rider has well under a second of gap. In a narrowed lane with a crossing truck, a chain-reaction crash is likely if you brake suddenly.
Manage it by:
- Signaling the group to spread out into single file with a larger gap (at least 2 seconds, roughly 22 m at 40 km/h) before entering the zone.
- Riding single file through the 3 m lane - no side-by-side riding.
- Using hand signals or a brief headlight flash to warn the riders behind of the truck and the narrowing.
- Not stopping abruptly in the zone; if you must stop, do it smoothly and early so the riders behind can react.
- Reforming the group after the zone, not inside it.
