Changing Lanes on a Bridge: Generally Unsafe and Often Illegal

Why It's Discouraged

• Narrow lanes reduce maneuvering margin.
• Elevation anxiety impairs judgment.
• High traffic density increases collision risk.
• Limited visibility (curves, structures).
• Wind/weather exposure affects stability.
• Vulnerable users (pedestrians, cyclists) share space.
• Emergency access must stay clear.
• Legal bans in many jurisdictions.

Best Practice

Stay in your lane crossing a bridge. If a change is essential, signal early, check mirrors/blind spots, and execute smoothly.
