No need to debate it - the speed limit on 2+2s is 100 and it's not going to change.
My only worry is that it's so easy to creep over that limit on such a road, I'm in danger of getting caught sometime.😯
It's a lovely drive and view for the passengers.
I switch on the cruise control for this very reason
Likewise! CC is the best way to avoid accidental speeding but many people in this country never use it at all for whatever reason. I often have the experience on the M8 of somebody whizzing past me only for me to whizz past them minutes later even though my speed is constant throughout. There was a time when CC was a premium feature but even my daughter's no-frills 10-year-old Ford Ka has it now.
I always use cruise control on motorways and the better N roads. Stops that creep where you find yourself matching the speed of the car in front or whatever.
Drove the full length of the N22 yesterday, both directions, for the first time since the extension opened. Fine road, pleasure to drive. Thought the camber was off twice when travelling West.
Google maps tried to take me off at the no longer existent roundabout !
Anyone know if there is a N22 'safety' whatsapp group?
I presume it's a speed van alert. Haven't heard of one.
Google maps still not updated. Very poor.
Speed certainly does not kill on well-engineered roads.
Gonna pretend I didn’t read that. Just obey the speed limits and you won’t need things like that!
This road is designed with a maximum speed of 100km/h in mind though.
Any idiot who exceeds the design speed of a road is obviously endangering themselves and other road users.
It's not. Roads are designed for speeds above the limit that's set on them. Otherwise you'd be driving at the design limit all the time, and that definitely wouldn't be safe.
You'd need to be doing around 20+ kmph above the speed limit to be exceeding the design speed.
AFAIK the motorways had a design speed of 160kmh with a speed limit of 120kmh, so I'll guess the 2+2s are designed for about 130kmh with a limit of 100kmh. Its a safety margin so its understandable.
Just stick on the limiter or the cruise.
Sure the road it replaces was 100km/h in places so the new road should be good for 120km/h at least :)
The following is from the current TII manual on rural road design. I’ll just leave it at this.
Those on ramps with no long merging lanes are enough reason to stay at 100km. Lack of hard shoulders too but the on ramps are ridiculously short, it'll just take someone speeding or not paying attention to the road to not move into the right lane and some poor soul who has just entered the road from the on ramp is going to be seriously injured or killed.
That's a very narrow perspective. Sure speed does not kill. However, the faster a vehicle is traveling when sh1t happens the higher the chance of its occupants ending up dead.
A well-engineered road is only one-third of the equation, what about the capability of the driver and the capability of the vehicle? There's a big difference between a very experienced driver in a well-maintained BMW M5 and a young lad/lass in a half-clapped-out Toyota Corolla traveling at 130km/h.
I'm not suggesting people should exceed the 120km/h speed limit, just using the 130km/h to reflect what is often the actual speed sometimes seen.
some dual carriageways (Ballincollig bypass N22) are 120km/h, it doesn't state those out of interest. the Ballincollig bypass may be built to a motorway standard but it's dual carriageway rules.
There are a number of 120Kmh sections of the M8 that are most certainly not fit or designed to be driven at anything like 160kmh. (And I am not referring to the 100Kmh Glanmire Bypass)
Totally agree with your suggestion abut the limiter or cruise control. I do it every time.
Yes, non-standard maximum speed limits such as 120 on the Ballincollig Bypass (when it would ordinarily be 100) or 100 on the M50 (ordinarily 120) are examples of what the Road Traffic Act refers to as a "special speed limit".
I posted that table because another poster stated, "roads are designed for speeds above the limit that's set on them." According to the TII manual, this is not correct in the case of roads with a limit of 100 and 120.
They aren't "on ramps", they are T junctions where traffic joining the new road is required to stop.
From the scenario you describe, it is most likely the "poor soul" who would be the cause of such an accident rather than someone on the main road speeding or not paying attention to the road. The person already on the road isn't required to move to the right lane and the driver joining shouldn't be expecting them to. The driver joining has to wait for a suitable gap in traffic before moving out.
"The person already on the road isn't required to move to the right lane"
An opinion which indicates a total lack of courtesy to other road users.
It's similar to the very Irish tactic of not facilitating a driver in lane 1 coming up behind a slower vehicle to pull out to lane 2 to overtake it.
Manners aren't laws, and the law says they are not required to move, and this is consistent with every other rule regarding right of way.
Most drivers do move out when they can in order to allow cars joining to do so more safely, but if you are the car joining you must assume that they will not make room for you, and wait for them to pass.
T junctions on a newly designed road national primary route, Sure what could go wrong ? If you or anyone else thinks drivers will restrict themselves to 100kph then ye are sadly mistaken. I've only been on it three times and was overtaken countless times and I drive at 100km.
I predict the turn onto the N22 towards Cork at Ballymakeery will be lethal when the unfinished section is open.
I never said I think drivers will restrict themselves to 100kph.
Where did I say you did ?
The person already on the road isn't required to move to the right lane, that is a fact not an opinion and remains the case whether it is courteous or not. I was making the point that drivers looking to join the road can't assume that others already on the road will move over, they need to wait for it to actually happen.
The poster I quoted seemed to think that only someone not paying attention would not move to the right lane which is nonsense, that driver is fully entitled to remain in the left lane.
You said; "If you or anyone else thinks drivers will restrict themselves to 100kph then ye are sadly mistaken".
I'm sure you will reply about not having said whatever but your previous post certainly implies that I thought that. I won't be replying to your response to this post in any case, this has gone too far already.
The word, 'if' is what I used.
"The person already on the road isn't required to move to the right lane, that is a fact not an opinion and remains the case whether it is courteous or not."
Not arguing that it's not a fact. However, such an attitude does indicate a lack of courtesy and any accommodation of the wishes of other road users. But then, in my experience, many Irish drivers are of the totally self absorbed type with little regard for others which is probably why we are among the most crash prone in Europe
