Single File, and Why Not Side by Side

Single file

Everyone in one line, two seconds apart, each rider free to use the whole lane. Use it any time the road stops being simple.

When: curves, intersections, bad surfaces, construction, and narrow roads with oncoming traffic. The MSF adds poor visibility and getting on or off the highway to that list.

Why single file in the curves

In a corner your line changes as you lean, and a staggered rider has nowhere to go if you run wide. Single file gives every rider the whole lane to pick a line in.

And it has to be your line. Never take the line of the rider in front. Pick your own, on what you can see and what you and your bike can do. Their bike, their tires, and their skill are not yours.

Changing formation

The lead calls it with the MSF hand signal: arm and index finger extended straight up for single file, arm with index and middle finger up for double file (staggered). Everyone passes it back. Then the group eases into place smoothly, with no sudden moves and no one braking hard to make room. When the road opens back up, the lead signals staggered and the group spreads back out.

Side by side

Two bikes level in one lane. Fine at walking pace in a parking lot, dangerous anywhere else. Neither rider has room to swerve, and you both lose the escape route the other one is sitting in.

When: parking lots and photos. Not on the road at speed.

Stopped at a red light is the exception. The MSF says it can be fine to close up side by side while you wait. When it turns green, the rider on the left goes first, and the group re-forms the stagger and the space cushion as it moves off.

In the video, MCrider covers coming prepared, staggered and single file, and why looking no further than the bike in front can lead a whole line of riders into one rider's mistake.
