i made a mistake in a group ride this summer with some new riders and some old . we came to a stop sign on a back road . now i usualy block intersections but was just getting use to my new bike and ddnt. my girl was leadin she's been riding 3yrs . she went her sister then her brother ( both new ) then came my turn and i saw a pickup coming but i went anyway, ddnt want to leave the new alone but behind me was another new girl rider . she stopped to wait for the truck to go by and one guy (not new) behind her looked and figurd he could make it easily and romped it. the last guy yelld stop but it was too late and the bikes hit eachother and went down. luckily nobody got hurt too bad but much damage to both bikes . yup it was an accident lol but now some ppl arent friends anymore and refuse to ride with eachother :-( wish i would have waited but i try to keep an eye on my old lady's sister ,she's the newest.
anyway lol riding in a group is alot of fun but has its responsabilities. you cant just ride the way you would when alone ;-) you have to pay extra attention to new riders even if they'r just 'new' to the group.
This is the reason for small groups and even smaller groups with new rides. You did not mention how many riders were in this group, but you said you usually block the intersection. Not a good idea. All you are doing is placing a line of vehicles behind you. These vehicles may contain folks that do not agree with you violation the traffic laws.
You could end up with vehicles spilting your group, making short passes into your group. And if your group attempts to prevent them from passing, you could end up with some bikes off the road. Remember, bike vs car, bike losses.
Plus you are riding with new riders. New riders mean longer intervals and more space for vehicle to pass and split your group. What's the problem with some bikes turning and other waiting for traffic to go by? They will catch up.
The group leader did not do their job. The rider at the head of the pack, is the leader. This leader should have given a basic do's and don'ts briefing before the ride. This is VERY important with new riders, or riders new to you group. It sounds like you had a gaggle of bikes, not a group.
At one time, everyone is a new rider. Everyone is, at times, new to group riding or riding with in a group. You have to ride your own ride, but the group leader as a responsiblity to let those in the group know what the precedures will be for stoplights, stopsigns, the group being spilt, routing, and final destination.
I still give a quick briefing when I lead. Even if it's the small group I normally ride with. If there's new folks, they get a full on briefing. If we have 10 bikes, the group is split into 2 groups of 5. And we don't block intersections or prevent others (cars, bikes or whatever) from passing us. It's just safer that way. If the group gets split up, everyone know where we are going. And as traffic resolves itself, the group will end up together again.
