 Most wide two lane roads are wide enough that one can overtake without crossing the center line, if a vehicle in front pulls into the hard shoulder (the carriageway including hard shoulders is 15–17 metres wide).Many future national road schemes in the Republic will use 2+1 roads or 2+2 roads, as opposed to wide two lane, which is considered to better suit lower capacities than that catered for by 2+1.Wide two lane, if finished to particularly high quality, with grade separated interchanges, has been shown to lead to a false sense of security (from the apparently high speed road) and more dangerous driving (due to the carriageways not being separated).
