One in three consumers pays over the odds for car insurance, according to the RAC.
The major crime most drivers commit against their personal finances is failing to shop around for the best premium and simply accepting your insurer's renewal quote, which is likely to be much higher.
Younger drivers can also grab themselves potentially much cheaper car insurance by opting for one of the new blackbox policies, these put a spy in your car to monitor your driving and reward those who are careful and don't drive at dangerous times.
Laura Keely, right, opted to have a little black box put in under the dashboard of her Vauxhall Corsa by Insurethebox.
In 2011 she paid £1,800 for a comprehensive policy. Twelve months on, her premiums have dropped to just £1,000 — a 44 per cent fall.
Whether you are male or female, old or young, follow our ten steps to lower premiums.
1. Shop around for the best dealsSavings of hundreds of pounds can be found if you shop around when you renew your cover.
Be careful though. When shopping around for car insurance, it's important to make sure that you are comparing like-for-like cover. Some policies may seem cheaper, but you may find you don't have the same level of cover when you have to make a claim.
Use an online comparison service to do the hard work for you. Put in your details and check the prices that come up. You can alter the excess that you are willing to pay and the mileage you will drive and get new quotes. Also check the insurers that don't feature in comparison sites, the big two are Direct Line and Aviva
promises to beat any renewal quote by another provider by at least £50 (renewals with M&S don't count). You also get European and legal coverage.
For the environmentally-conscious, The Green Car Insurance deal not only plants trees on your behalf, but throws 90 days free travel insurance and an 25 per cent discount on your car cover into the deal.
Churchill offers a 24-hour legal advice line, an uninsured drivers promise and a five year servicing deal. Experienced, safe drivers could also get an 80 per cent discount for cover of eight years or more.
Tempcover insurance could be a good option if you are after cover for a short period of time and Provisional Marmalade have a decent offering exclusively structured for young drivers.
2. Don't put everyone on your policyEnsure that only regular drivers are named on the policy. You can always add someone for a few days when they really need to drive the car.
3. Protect that no-claims bonusA long no-claims bonus is the single best way of cutting car insurance costs, so protect it.
This may increase the premium by a few pounds, but this fades into insignificance against the potential loss of a 90 per cent discount on a premium of several hundred pounds.
But the definition of a protected no-claims bonus can vary widely between insurers.
Though accidents caused by another driver will normally have no impact on such a bonus, those caused by the insured could. The key is to always check the policy carefully.
4. Take a higher excessIncrease your voluntary excess. Agreeing to pay more towards the cost of any accident repairs will bring down premiums. If you are not at fault in an accident, the excess can be recovered.Beware being tempted to allow it to rise too high, however, especially if you have a lower value car.
5. Secure your carFitting an approved alarm, immobiliser or tracking device can attract a discount of around 5%. Many newer cars will come with these as standard, so make sure you check if you have them and then declare them.
FIVE STEPS THAT CAN CUT THE CAR INSURANCE BURDEN1. Compare prices: Use an online comparison service to do the hard work for you.
Put in your details and check the prices that come up. You can alter the excess that you are willing to pay and the mileage you will drive and get new quotes.
Also check the insurers that don't feature in comparison sites, the big two are Direct Line and Aviva. This is Money's car insurance search is powered by MoneySupermarket and will search more than 130 insurers for you. Try it out here.
2. Haggle! The car insurance market is notoriously competitive. Once you've been on This Is Money's comparison and found your cheapest price (below), get on the phone and start bargaining!
3. Avoid paying monthly charges: Direct debit installments generally come hand-in-hand with high interest rates.
An alternative is to borrow the money on a 0 per cent purchase credit card and then clear it within a year. [Check the best 0% purchase credit cards here]
4. Think outside the box: An accelerated no-claims bonus, such as Admiral's Bonus Accelerator, could give you a year's no claims bonus after just 10 months.
5. Named drivers and friends and family: If you have previously been insured as an additional driver on another policy, see if you can transfer a no claims bonus to your own insurance coverage.
Some insurers do this, including Direct Line. Try for a discount by insuring two or more vehicles between friends or family members with the same firm.
6. Do less milesThe fewer miles the car covers, the greater the saving.
For example, a reduction in annual mileage of 5,000 miles could save a typical 35-year-old driver about £50 a year in premiums.
A cut of 10,000 miles a year could save more than £100.
But you must be honest about your annual mileage, as inaccuracy will jeopardise any claim.
Check your use cover - if you don't use your car to drive to work or for business - both things that increase your premium - you may be able to get a cheaper rate.
7. Think carefully about adding young driversAdding a young, inexperienced driver to your policy can be a false economy, especially if you have a large or higher powered vehicle.
The premium will still be affected by the youngest driver and he or she may not have a no-claims bonus. Insurers have also been cracking down on fronting, where parents insure cars in their name for children to cut costs, so make sure if you are the policyholder on a car driven by your children that you are actually its main driver, or that you declare otherwise.

8. Watch out for insurance trap cars If you decide to change your car, check with your insurer if the model will have a significant effect on the premium.
Sporty cars can attract a high premium and often a slightly different model or smaller engine can make a big difference in your favour.
It will also probably save you on petrol too!
9. Remember what the garage is forIf your garage is full of junk, clear it out and use it for your car.
Insurers like cars kept in garages overnight and this can dramatically cut your premium.
Aside from the benefit of not having to scrape the ice off in winter, there is a higher risk of theft by keeping the car on the road, so keeping it in the garage will be reflected in your premium.
10. Be a better driver and sign up to a blackboxBlackbox policies, where the insurer instals a system in your car to monitor your driving, reward those who drive carefully.
Officially called telematics, these check your speed, your handling and how cautiously you drive, and also whether you are on the road at perceived dangerous times - ie the early hours of the morning.
They can cut premiums substantially once you start proving you are a good driver. The biggest win is for those whose premiums are high, especially young drivers.
