Types of Three-Wheel Vehicles
Two-wheel motorcycles are single-track vehicles; motorcycles with sidecars are double-track and trikes are triple-track (two front wheels or two rear wheels). p. 36
Differences between Two-Wheel Motorcycles and Three-Wheel Vehicles
A three-wheel vehicle is more stable than a two-wheeler but can still tip over or lift a wheel, so watch body position, speed and loading. p. 36
Swerving
A three-wheel vehicle isn't as maneuverable as a two-wheeler, so look well ahead to avoid sudden turns; swerving is seldom the best way to avoid a collision, and hard braking may be better. If you must swerve, brake before or after, never during, and don't try it without proper training. p. 37
Cornering and Curves
Park a three-wheel vehicle parallel to the curb, which makes pulling away into traffic easier, and set the parking brake or leave it in gear so it won't roll. p. 37
Stopping Quickly
On a standard trike (one wheel in front, two in the rear) the two rear wheels have more braking power, because weight doesn't shift to the front wheel in hard braking. p. 38
Stopping
Check whether your sidecar has brakes: without them, stopping distance and handling change, and you may need to steer slightly toward the sidecar when braking. When accelerating, steer slightly away from the sidecar to keep a straight line. p. 39
