Splitting with hazards on used to be a rare sight, but we’ve been seeing this in the wilds of commute-land more frequently of late. Maybe because it’s “riding season” again and riders that keep their machines safely tucked away in clean, dry garages during California’s downright inhospitable winters are just getting their mojo back. Maybe just (dumb, for sure) luck. But it warrants a come-to-Jesus talk.
When we split lanes with our hazards on, we send the wrong message to drivers, and we do that way too much (splitting too fast, clipping mirrors, and so on) already, so please turn off your damn hazard lights.
Two options here:
1. If you suck so bad at splitting that you actually are a hazard to your fellow road users, please stop splitting lanes for now. Go practice low speed maneuvers, braking, situational awareness, and all that good stuff. When you’re confident, but more importantly, competent, you can join us in the split again.
2. If you’re just trying to increase your conspicuity, please turn off your hazard lights and ride to your local shop, where you can purchase all sort of items to help with this in a way that doesn’t say, “Hey, something is wrong.” High-vis gear (helmets, jackets, vests) is great for this very purpose, so great, in fact, that it’s called high visibility gear. Got it?
Of course, there’s also the California vehicle code, which states in section 25250-25282, “Flashing lights are prohibited on vehicles except as otherwise permitted.” Those otherwises include turn signals (duh), disabled vehicles, to warn of hazards or accidents, and a whole bunch others, including headlight modulators on bikes. What’s not included, however, is lane splitting.
