However, driving significantly below the speed limit can be deemed an offence under Australian Road Rule 125.
While you're more than likely to gain the ire of drivers behind you, remember that driving under the speed limit is legally fine, but driving excessively slowly can land you in a bit of hot water.
Drivers everywhere know they can be fined for speeding, but motorists can also be potentially fined for driving too slowly. Driving too far below the speed limit is an offence as it can be considered obstructing the path of other road users.
On a road with one lane in each direction, going 10-mph is legal, but can impede the flow of traffic. If it's safe to do so, drive closer to the max speed limit.
“If you are travelling on a Freeway you must travel no slower than 20km/h below the speed limit unless there is traffic congestion or road conditions dictate,” the WA Police FAQ site states. But, there are instances of slow driving that may not end up getting you in trouble.
Although it's far more common to be ticketed for speeding, it's also possible to get a citation for driving too slowly. Generally, it's illegal to drive so slowly that you blook or impede the normal flow of traffic.
Queensland's Manual of Uniform Traffic Control Devices (Speed Controls) states that 60 km/h (37 mph) is the general minimum speed limit for traffic-carrying roads.
What speed is considered too slow? Going under 40 miles an hour is generally considered driving too slowly.
In short, there is no offence in driving slowly in British Columbia unless you do not have a safety reason or are driving contrary to the officer's instructions. This is one of those laws that can differ depending on which province or state you happen to be driving in.
§ 91.117 Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).
Area Speed Zone – Applied to a network of roads. School Zone – Related to a school and applied to a network of roads. Heavy Vehicle Zone.
The Queensland Road Rules (QRR) provide that a driver must not unreasonably obstruct the path of another driver by driving too slowly. The penalty for this offence is $133.
Simply driving a bit slower than the cars around you is fine, but according to the Australian Road Rules, a driver must not “unreasonably obstruct the path of another driver or a pedestrian”. For example, driving 20km/h in an 80km/h zone without a suitable reason could land you in trouble with police.
Where a driver exceeds the signed speed limit by 45 km/hr or more, they may be charged with the offence of driving at excessive speed, see: Excessive Speed. A speed limit sign often indicates the speed limit [Australian Road Rules r 20] or if there are no signs, the default speed limit applies.
Sleeping in your car could be a costly error
With Queensland being the most likely spot to punish you for the offence, you need to be wary that the fine varies from region to region with some notable inclusions being: Brisbane: $550 fine. Cairns: $275 fine. Gold Coast: $150 fine.
This tolerance deducts two km/hr from a vehicle's detected speed for fixed digital safety cameras. For mobile cameras, a tolerance of three km/hr or three per cent for speeds over 100km/hr is deducted. Police can also apply an additional tolerance at their discretion. How do red-light cameras work?
Slow drivers are the ones that don't like to speed because there afraid of getting caught or those who simply rather not put all there attention on the road. Slow drivers generally don't create a serious problem because they only go 10-15 mph under the fastest safe driving speed for the road (not the speed limit!).
Generally, 5–10 mph over the speed limit. I drive slower if I think conditions are such that I need to be safe.
Slow Down
Your tires lose about one-third of their traction on wet pavement, so, as a rule of thumb, when driving on wet roads you should reduce your speed by about a third. For example, if the speed limit is 45 mph, you should drive about 30 mph in the rain.
But driving slower than the posted speed limit in normal conditions can affect the flow of traffic and endanger others, says the New York State DMV. Drivers going below the minimum speed can be charged with a moving violation for blocking or impeding traffic.
Going slower theoretically saves fuel, because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission – and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.
SPEED On the highway, if road conditions are poor, or visibility is reduced, you should slow down to a speed that will allow you to stop within the distance you can see. In cities or towns with restricted speed zones, the speed limit does not change at night, but visibility does so you should slow down.
There was no absolute speed limit in the Northern Territory before 1 January 2007 but maximum speed limits are now posted throughout the Stuart Highway. Previously, drivers were simply required to drive at a safe speed to suit the conditions.
An L-plate driver in Adelaide has been busted driving at 253km/h. The 20-year-old man was recorded travelling a full 143km/h over the speed limit, at one of the highest speeds ever captured on the state's roads.
