Vehicle Maintenance and Breakdowns

Vehicle maintenance

Proper vehicle maintenance is essential to keep yourself and others safe on the road. If you drive, you are operating a fast-moving piece of heavy machinery that needs to be kept in the safest possible condition. Good maintenance can save you money as minor repairs which are delayed often turn into more expensive and serious issues later.

Make sure you get your Warrant Of Fitness (WOF) when it's due and service your vehicle is serviced in line with what is recommended in your handbook. For many vehicles, WOFs are only carried out annually, but things can go wrong between checks so get your vehicle serviced in between WOFs. Some mechanics offer free safety checks or special servicing deals in between your WOF to help you stay safe.

Most vehicles will require an oil change every 10,000-15,000 kilometres. If you check your oil at home and it is black, has a burnt smell or is thick or sludgy, it is likely overdue for a change. Not getting an oil change can cause your vehicle to overheat, lose lubrication or result in parts grinding or blocking up. This results in poor performance, reduced fuel economy, and potentially catastrophic engine failure.

Faulty batteries are also a common problem. We recommend testing them annually before cold weather sets in. Many garages offer free checks.

Company vehicles

If you're driving an employer's vehicle, speak to them about who is maintaining it and when it was last checked.

Choosing the safest vehicle

Buy the safest, most reliable vehicle you can. To find out the safest car models, visit ANCAP, which tests and rates them. You can also check vehicle safety through the RightCar website.

Pre-purchase inspections

Before buying a second-hand vehicle, get it checked over by an independent, qualified and experienced mechanic. It's better to pay for a mechanic than buy a car that isn't safe.

Pre-drive inspections

You should carry out regular 'walk-round' checks of your vehicle and before any long journeys. This check only takes a few minutes. The main things you should look out for are:

Tyre tread wear. Look out for tread wear indicator bars on tyres - small bumps in the main grooves which indicate the minimum tread. Change your tyres well before your tread gets to the legal minimum (1.5mm in NZ). If you drive with tyres worn down to below the legal limit, you could face a $150 fine, or it could cause a deadly crash.
Tyre pressure. Check your tyre pressure regularly, when the tyres are cold. The correct pressure will be written in your vehicle's handbook. There is also usually a sticker placed inside the driver's door. Free tyre pressure checkers and air are available at most service stations. Badly-inflated tyres can mean you use more petrol.
General tyre condition. Check for cracks, bulges or bubbles on the sides of your tyres. These are signs that the tyre is damaged and at risk of blowing out. If you see any of these, get the tyre checked by a professional, and replaced if necessary.
Lights are working. Check lights are clean and bulbs aren't blown (reflect against a wall, or ask a friend to help).
Oil, water and fluids. Check oil and water levels, and other fluids such as power steering, windscreen washer and brake fluid, are well above minimum levels.
Wiper blades. Check they are in full working order and replace if worn.
Wheel fixings. Check wheels and wheel fixings for defects, including loose nuts.

Warning signs when driving

As setting off and while on your journey, look out for:

problems with, or noises from, your brakes. Brakes usually squeal or make a loud noise when worn
warning lights on your dashboard
excess noise or smoke from the exhaust, or from under the bonnet
fluid leaking from under the vehicle
smell of hot electrics, fuel, or a burning smell
unusual sounds from the engine
a pulling sensation from the steering

If you have any suspicion at all there's a problem with your vehicle, take it to a garage immediately.

Breakdown advice

Breaking down on the road can be a frustrating, unpleasant, and sometimes dangerous and scary, experience. Every year, people are killed or seriously injured while stopped on the roadside, but many drivers don't know how to keep safe in the event of a breakdown.

Motorway breakdowns

In a breakdown situation, the most important thing for drivers to consider is the safety of themselves and other road users, particularly on high speed roads like motorways. Hard shoulders are extremely dangerous places.

If your vehicle develops a problem on the motorway:

If your car develops a fault but you can continue driving, leave the motorway at the next available exit and stop at the service area or another safe place
If the problem requires you to stop immediately, pull onto the hard shoulder and stop as far away from the traffic as you can, with the wheels turned to the left, if possible next to an emergency phone
Never use a warning triangle on the hard shoulder of the motorway, as walking along the hard shoulder to place a warning triangle puts you at risk of being hit
Never sit in your vehicle on the hard shoulder, even if the weather is bad. This is dangerous as you are at risk of being struck from behind at high speed
Put on your hazard lights and get out on the left hand side, and wait on the verge, well away from traffic
Anybody who is unable to leave the vehicle, for example someone with mobility issues, should wait inside the vehicle with their seatbelt securely fastened.

Never be tempted to try and fix your vehicle on the hard shoulder yourself - this is dangerous. Call for help instead, using an emergency phone if one is accessible without walking along the hard shoulder. Emergency services will be able to tell your exact location from the phone as each phone has a number. Phones are dark blue with a red reflective phone icon, and white reflective stickers giving the ID of the phone. Phones are often located behind barriers to give you protection, but you should always make the call facing traffic.

Using the hard shoulder is legally permitted in only three instances: in a breakdown, an emergency, or if being pulled over by the police. Making a phone call, taking a toilet break or reading a map are not acceptable reasons to stop in the hard shoulder.

Breakdowns on any other type of road

If you breakdown somewhere other than the motorway, follow these guidelines to keep as safe as possible:

If it is possible, avoid stopping in a dangerous place, such as on a roundabout, on a corner or near a brow. If you can safely keep driving for a short distance, drop your speed, use your hazard lights and try to pull off the road completely or in a location where you’re clearly visible
If you have to stop on a road, switch your hazard lights on. Only display an emergency triangle at least 45 metres behind your vehicle if it is safe for you to do so. Do not put yourself in a risky situation in putting out the triangle, and never use one on the hard shoulder of a motorway
Do not attempt to fix your vehicle yourself at the roadside. Call a breakdown service
Switch your engine off and stand as far away from the road as possible so you are not close to passing traffic
If you are involved in a crash that is serious, obstructs the road, or involves injuries, call the emergency services as soon as possible. If you have first aid training, provide appropriate, immediate help to anyone who is hurt

Make sure you are prepared in case you breakdown by:

Carrying a mobile phone so that you can call for assistance, and use a map app to provide your location when calling for assistance. However, be aware, you may not have signal if you breakdown somewhere remote.
Keeping an emergency kit in your car, which should have a torch, a warning triangle, warm clothes and a reflective jacket or vest, and bottled water.
Having a jack, jumper cables or battery jump pack and snow chains in your vehicle also, and familiarising yourself with how to use these items before you need them.
