Oregon Motorcycle Hazards and Surfaces Practice Test

What the Oregon Motorcycle & Moped Manual says about hazards and surfaces

• Handling Skids: Rear-Wheel Skids

  A skidding rear wheel, caused by too much rear brake pressure, is dangerous and can lead to a collision; with the rear wheel locked you can't change direction. If it starts to skid, release the rear brake right away and reapply it smoothly. p. 37

• Swerving

  Swerving may be right when stopping won't avoid a collision. p. 37

• Grooves and Gratings

  Riding over rain grooves or metal bridge gratings may make your motorcycle weave. Keep a steady speed and ride straight across. p. 39

• Crowned Roads

  A crowned road is higher in the middle than at the sides. Use caution and slow down when cornering on one, because ground clearance is reduced and you have less lean angle available than on a flat road. p. 41

• Work Zones: Gravel and Grooves

  In work zones, motorcycles lack four-wheel stability, so slow down. p. 41

• Work Zones: Tar, Uneven Pavement and Objects

  In work zones, avoid oil or fresh tar if possible, or go slowly without sudden moves. p. 41
