Answer in brief
The actions that lower a high premium, in order of typical impact: compare several insurers (often 20–40% for the same coverage), raise deductibles (15–25% off collision and comprehensive), drop collision and comprehensive on low-value cars, enrol in telematics (5–30%), bundle home or renters (10–25%), correct your mileage and vehicle use, and claim every discount you qualify for. Cutting liability limits is not on the list—it saves little and exposes you to the largest losses.
Actions ranked by impact
| Action | Typical saving | Trade-off |
|---|---|---|
| Compare 3–5 insurers | 20–40% | Time; possibly a new company |
| Raise deductibles to $1,000 | 15–25% of collision/comp | Pay more after a claim |
| Drop collision/comp on a low-value car | Up to 50% of premium | Pay for your own car's damage |
| Telematics programme | 5–30% | Share driving data |
| Bundle home/renters | 10–25% | One insurer for both |
| Correct mileage / usage | 5–15% | None if accurate |
| Pay in full | 5–10% | Cash flow |
| Defensive driving course | 5–10% | A few hours |
| Other discounts (student, paperless, autopay, safety) | 2–10% each | Minimal |
What not to cut
Liability limits. Dropping from 100/300 to 25/50 saves relatively little because liability pricing is driven by frequency, not limit, and it leaves you exposed to the one kind of claim that can exceed your savings. Uninsured motorist coverage is similarly inexpensive for what it protects.
The order to do it in
- 1
Read your declarations page
Note coverage, deductibles, discounts, surcharges and the vehicle symbol.
- 2
Decide the coverage you want
Fix limits and deductibles; decide about collision/comp on each car.
- 3
Get quotes for that exact coverage
Three to five, same inputs. See when to switch.
- 4
Ask your current insurer to match or re-rate
Mention discounts you may be missing.
- 5
Switch without a gap
New policy starts the day the old one ends.

Questions & answers
What is the fastest way to lower car insurance?
Compare quotes from several insurers for your exact coverage. The spread is usually larger than any single discount.
Should I lower my liability to save money?
No. It saves little and exposes you to the largest possible losses.
Does raising my deductible really help?
Yes—typically 15–25% off the collision and comprehensive portion of the premium.
