Study Notes
Emergency Maneuver Techniques
- Threshold braking: maximum pressure short of lock-up, releasing gradually to avoid lock-up while maintaining maximum pressure throughout.
- 9 and 3 Steering: light finger pressure, heavier pressure with thumb; excellent for quick steering needs, body balance, and quick access to dashboard control items.
- Shuffle Steering: avoid crossing hands by sliding the wheel in small amounts; best for gradual turns.
True Apex Turn
- The true apex of a turn is the geometric high point on the inside of a turn.
- The correct Line of Travel through a true apex turn is outside-inside-outside.
- For a left turn, move out to the right side of the roadway, brake in a straight line, coast to the inside at the apex, then accelerate to the outside/right edge.
- For a right turn, move to the left side of the roadway, brake in a straight line, coast to the inside at the apex, then accelerate to the outside/left edge.
- The vehicle should cross within two feet of the apex at a 45-degree angle.
- Car will travel in a large radius, allowing for higher speeds and less stress on the vehicle.
Route Selection and Warning Devices
- Factors to consider when selecting a route: traffic density, pedestrian traffic, slow moving traffic, line-of-sight conditions, and day of the week.
- Avoid roads with heavy traffic, slow moving traffic, or poor visibility.
- One-way streets offer the advantage of avoiding on-coming traffic but the disadvantage of approaching all vehicles from the rear.
- Consider selecting a route that offers the least amount of steering and speed adjustment requirements, approaches and intersections with acceptable line-of-sight and legal right-of-way, and the quickest, most direct route.
Emergency Warning Devices
- During daylight, use headlights in conjunction with emergency overhead lights.
- During hours of darkness, high beam lamps can obliterate the emergency lights and blind oncoming drivers.
- Sirens are often required by statute, regardless of the time of day.
- Emergency lights and sirens are not a substitute for caution and utilization of mastered driving skills.
- Factors that affect the siren's audibility and the light's visibility include weather conditions, vehicular traffic, location, and pedestrian traffic.
Safety Techniques Relating to Pursuit Driving
- Common pursuit driving tips: vary the pitch of the siren, tighten seatbelts, talk on the radio as little as possible, flash lights when approaching another vehicle, and use high beams as much as possible.
- Know the area, don't depend on your siren to move other vehicles out of the way, and know your limitations and your vehicle's limitations.
- Keep wheels well away from pavement edges, slow down at red lights and stop signs, and don't travel at high speeds in opposing lanes.
- Avoid pulling directly beside or in front of the violator's vehicle and don't attempt to ram or nudge the violator's vehicle.
- When to abandon a pursuit: if an officer begins to feel or suspect that they are driving over their and the vehicle's limitations, or if the officer feels or begins to suspect that the vehicle has a malfunction.
