Key Takeaways

  • Part D has TWO coverages: Collision (damage from impact with another object) and Other Than Collision/Comprehensive (all other physical damage)
  • COLLISION covers damage from hitting another vehicle, object, or overturning — regardless of fault
  • OTHER THAN COLLISION (OTC) covers theft, fire, glass breakage, flood, hail, vandalism, and hitting animals
  • Collision typically has a DEDUCTIBLE ($500-$1,000 common); OTC deductibles are often lower or zero for glass
  • Hitting an animal (like a deer) is covered under OTC/Comprehensive, NOT Collision

Part D: Physical Damage Coverage

Part D protects YOUR vehicle from physical damage. Unlike Part A (which pays for damage you cause to others), Part D is first-party coverage for your own car.

The Two Parts of Part D

1. Collision Coverage

Definition: Covers damage to your vehicle from impact with another object or vehicle, or from overturn.

Covered Events:

  • Hitting another vehicle
  • Hitting a tree, guardrail, building
  • Pothole damage
  • Overturning (rollover)
  • Backing into a pole

2. Other Than Collision (OTC) / Comprehensive

Definition: Covers damage from causes OTHER than collision.

Covered Events:

PerilExample
TheftCar stolen
FireEngine fire
Glass breakageWindshield crack
FloodWater damage
HailHail dents
WindstormFlying debris
VandalismKeyed car
Falling objectsTree limb
EarthquakeGround movement
Hitting an animalDeer strike
RiotCivil disturbance

Exam Alert: Hitting an ANIMAL is covered under OTC/Comprehensive, NOT Collision. This is frequently tested!

How Part D Pays

Actual Cash Value (ACV)

Part D pays the lesser of:

  • Actual Cash Value of the vehicle
  • Cost to repair

ACV = Replacement Cost - Depreciation

Total Loss Determination

If repair cost ≥ ACV, the vehicle is a "total loss":

  • Insurer pays ACV
  • Insurer takes the vehicle (salvage)

Example: Partial Loss

DamageValue
Repair cost$5,000
Vehicle ACV$15,000
Deductible$500
Insurer pays$4,500

Example: Total Loss

DamageValue
Repair cost$12,000
Vehicle ACV$10,000
Deductible$500
Insurer pays$9,500 (ACV minus deductible)

Deductibles

How Deductibles Work

You pay the deductible; insurer pays the rest.

Common Deductible Amounts

CoverageCommon Deductibles
Collision$500, $1,000, $2,500
OTC$0, $100, $250, $500
Glass (OTC)Often $0

Deductible Trade-off

DeductiblePremium Impact
$250Higher premium
$500Moderate premium
$1,000Lower premium
$2,500Lowest premium
