lane

In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
Some roads and bridges that carry very low volumes of traffic are less than 4.6 metres (15 ft) wide, and are only a single lane wide. Vehicles travelling in opposite directions must slow or stop to pass each other. In rural areas, these are often called country lanes. In urban areas, alleys are often only one lane wide. Urban and suburban one lane roads are often designated for one-way traffic.

    Lane Keep assist Green Icon

    I have been going round in circles with MG Customer Services trying to find out when this icon is meant to be on. The manual says when LKA is activated. On my car this icon is not showing when LKA is set in the MG Pilot screen I do not see this icon on the cluster display on my MGS5...

    TJA vs LKA

    TJA uses both camera and radar. If the camera provides insufficient information about lane markers, it goes into 'follow mode'. LKA uses the camera as well. How come in TJA mode the camera shows lane markers, but on the same road (with double solid markers) LKA cannot?

    LANE ASSIST RECALL

    So I was in my local MY dealer's on Tuesday , and was advised that there was a recall on the MG4. It was a Lane Assist recall and they did the upgrade there and then. I don't use Lane Assist at all; indeed I turn it off each time I get into the car, but I wondered if you all have had the same...

    Merged thread: Automatic Emergency Braking activating for no reason

    [ Moderator: Merging threads on this important and emotive issue. Please use this thread for all unwanted AEB issues. ] Driving out of a Morrison's supermarket at the weekend my MG4 suddenly decided to [for the want of a better phrase] emergency brake. This happened once before in the new year...

    Lane Keep Assist possible fix

    I won’t say this is a fix to the problems associated with lane keep assist, and those that keep turning it off each time they get in the car, but this is a solution I have been using to make it work “normally”. If you try it, and it works for you, come back and say so, so that others can get...

    Big Truck Scared the Car... 😨

    Was queueing in the right hand lane of a dual carriageway (approaching roundabout) with the left lane clear, with ACC doing the crawl/stop start, when a large truck came at speed up the inside lane (the type where the whole car rocks when it passes!). Poor car got quite the scare as it...

    Lane Assist reactivation.

    My MG4 Excite 51 was purchased in Australia in Jan 2025. Built July 2024 with all software updates. If Lane keeping assistance is disabled and confirmed upon pressing the brake (to engage gear) LKA is immediately reactivated. I have to engage Drive before deactivating LKA. If the car is stopped...

    Front Detection/Anti collision

    Does disabling LKA also disable Front Detection/Anti Collision. I always have LKA disabled as it is easily confused and notice that I am able to get very close to things (walls, cars and people) when moving very slowly, without any warnings.

    Lane departure warning system reacts incorrectly

    Unfortunately, I have already noticed several times that the lane departure warning system reacts incorrectly. When I come onto the centre line with the wheels, the car tries to pull me into oncoming traffic, when the wheels touch the line of the hard shoulder the car tries to pull me off the...

    Lane assist issue?

    I'm having the PD052 update applied in a week - the over-revving is still occuring but I manage it better with heating down and more controlled driving. But before I take it for the update I wonder if any of you have had any issues with lane assist. I've driven the car 2 months and on a few...

    Lane Keeping gets confused by passing cars?

    New MG3 Hybrid+ with left steering wheel Under Vehicle->MG Pilot there is a "Lane Departure Assist" section. At first I tried turning it off, or setting the "Mode" to something less strict. Yet, after turning the car off and on again, the "Lane Departure Assist" reverts to on, with Mode=ELK (I...

    MG4 lane keep still an issue?

    Hi, I've been looking at getting an MG4 for a while. What's holding me back is the negative stuff I've read about lane keep assist i.e. that it's a bit unpredictable and even dangerous under certain conditions. I think the current firmware is R63, has this issue been sorted out in this FW...

    Slamming On (Again)

    Mrs S has been gadding about while I've been holed up in the hospital. Heartless bugger. She even went out to one of our regular scofferies without me. Anyhow, she had another slam-on scare where His Lordship jammed on the anchors as he thought she was going to crash into some parked cars she...

    TURNING OFF MG4 Lane Departure Assist.

    After almost 2,000km in our new MG4, I have now realised that turning off a number of the "safety" features is best for me. One of them is lane departure assist. However, I have noticed that, even if I turn OFF LDA prior to my moving, (and the blue "on" marker turns to grey), LDA will appear as...

It's a great little car but we've literally been wrestling with its very well known lane keeping assist issues. We live in rural part of Ireland and the LKA makes the Car very...

    Mg4 Lane assist hardly activating

    I have read lots of forums about MG4 lane assist too aggressive etc. But i seem to have the opposite issue mine hardly ever initiates so on the dashboard the lka symbol mostly stays white and rarely goes green. If it does work it might only go green for a few seconds. This happens on good roads...
