First of all, the speedometers of most vehicles are designed to overestimate the speed of the journey. International law has long required modern cars to exaggerate real speed. The standard applicable to many vehicles sold in New Zealand is a European standard that specifies that speedometers must not display speeds lower than the actual speed of the vehicle, or a speed more than 10% to 4 km/h higher than the actual speed of the vehicle. When speeding tickets are issued, drivers are often immediately rejected, insisting that they did not exceed the legal limit when they were caught. What`s the reason why GPS speedometer isn`t legal, I think if you`re out of range or you`re going through a tunnel or something like that? I recently installed a limited-slip differential from the aftermarket. This diff is tight and as such makes some hits and squeaks of tires at low speeds. Are there laws for this type of change? You have a limited slip diff that is completely legal. A locked diff (gears or welded coils) is not legal. An ultrafast limit slip (LSD) diff (for which some are notorious) can cause the same type of low-speed”grip” at tight radius that causes a coil or diff to be locked. Adding a friction modifier to your diff oil can relieve the binding effect. If they drive too slowly, they can cause subsequent drivers to take unnecessary risks when overtaking and reduce subsequent distances to potentially dangerous levels. Although the speedometer is just a speed display, it`s safe to say that if you`re driving near or even a fraction of the speed indicated on your speedometer, you`re comfortable within the legal limits for that piece of road. A motorcycle that was originally sold for off-road use (for example, an agricultural motorcycle or an off-road motorcycle) and therefore does not comply with road traffic rules and is not included in the system.
Can it meet legal requirements and be put on the road? Usually, no. The standard bike should demonstrate compliance with all applicable NZTA access requirements before an LVV certifier considers changes, which usually cannot be done. However, some bike manufacturers sell road kits to legally convert their trail bikes. You can`t get around this by asking LVV to certify it as built from scratches, as it`s a mass-produced bike. Flamethrower kits for exhaust gases and electronic cut-outs – legal or not? They are not legal. The in-service virm (exhaust/exhaust system) certification, section 11-1, Reasons for refusal, paragraph 4, states: “The exhaust system shall be designed or modified in such a way that its operation or efficiency can be easily disturbed, for example if the driver is able to interfere with the exhaust system by operating a manual switch, or if the exhaust is equipped with a flamethrower kit.” A “bimodal” system can be installed if it does not have a switch operated by the driver, something like the system installed in a high-volume manufactured vehicle (HSV / Audi, etc.) would be fine, but it cannot exceed the applicable noise limits in both modes. Is it legal to install a full seat belt in my car? For a production road car, the only way to have a full belt is a MotorSport NZ or NZ Drag Racing Association authority card. Belts are also allowed in vehicles built from scratches such as sports cars and kit cars, but only if they have a single row of seats and only when they meet other specific requirements.
For more information, refer to NZCCM Chapter 14.32, Section 14: Seats, Seat Belts and Anchorages. I would say that GPS is not legal for the exact reasons you specify. Must work all the time. Tunnels/roads covered with forests etc. would not give you any reading. Be warned: as motorists should be accustomed to now, the presence of police and speed cameras continues to increase during a long weekend or extended holiday and the tolerance limits around the legal speed limit are reduced. GPS speedometer is more accurate than mechanical speedometers and works independently of the vehicle, so it is not subject to factors such as tire pressure, circumference, differential ratio, etc. This wireless unit is also safer on the go, as the large LCD screen can be mounted on the windshield and allows you to check the speed without having to take your eyes off the road. You can also take it with you wherever you go, use it on your boat, mountain bike or bike. Supplied with suction bracket, USB cable and cigarette lighter charger. Mickey Thompson ET Street tires are apparently classified as road tires because they have a DOT rating, although I`m not sure what it is.
Are these tires really homologated for the road? There are only about 5 grooves on the tires and they are only about 1mm deep, I doubt they are very good in the rain. Tyres shall have a minimum tread depth of at least 1,5 mm (without tread depth or tread depth indicators) over the entire circumference of the tyre in all main grooves containing tread depth indicators or, if the tyre does not normally have tread depth indicators, on at least three quarters of the tread width. Therefore, the Mickeys do not stick to it. Can I mount transparent taillights for my Honda? The problem is that I`ve heard conflicting stories from my buddies about their legality (or illegality). The lights have red and orange bulbs with them, but otherwise they are completely clear. If the vehicle conforms to the entrance, all replacement taillights, transparent or standard, must meet one of the standards approved by the NZTA. Before buying, check if they have any of the standards marked on the plastic outer lens. If not, ask the supplier to prove to you, through documented evidence, that they actually meet an approved standard and to keep a copy. The approved standards are UNECE Standards 7, 76/758/EEC, FMVSS 108, ADR 49, JIS D 5500 or any other Japanese technical standard.
However, if the vehicle is already registered, the requirements are more flexible and you can change them as long as they meet the VIRM, In-Service Certification, General Vehicles (Lighting), Section 4, Condition and Performance requirements. Gimbal shaft handbrakes – are they legal? A gimbal shaft handbrake can be used as long as the vehicle is equipped with a double-circuit brake master cylinder. This is described in detail in Chapter 8 (Braking Systems) of the NZCCM in paragraph 8.9.4. As mentioned above, the odometer is not a legal requirement for WOF and is not a legal requirement in a gasoline vehicle period. GPS odometers were explicitly declared illegal by the latest WOF VIRM update in April this year. It also helps prevent manufacturers from being held responsible or charged for their vehicles constantly driving above the legal speed limit through no fault of the owners. I know that cut coil springs are illegal, but what about heated and compressed springs? I have all these things in my job to do it, but I was wondering if I should do it or not? Changing the length of a spring by heating and resetting the free length can only be done by a recognized spring manufacturer who tempers the spring with the right process for this type of steel. This involves a process such as soaking the spring at a precise high temperature, quenching in oil and reheating at another high temperature, and slow cooling. If the process is not carried out correctly with the right temperatures and evenly throughout the spring, spring sags or breaks after a short time.
