Traffic has returned to normal after hauliers protesting in Dublin today ended their protest.
There was no major disruption beyond the normal heavy traffic after the Road Transport Association (RTA) agreed to scale back the numbers taking part.
Motorists had been warned to avoid the M50 and were told there would be major disruption on the M1, N3, N4 and N7.
The truckers staged the go-slow on both sides of the M50 between the M1 interchange and the Ballymount exit. A group also blocked Dublin port in the protest at the city centre HGV ban and tolls.
Gardaí broke up the convoy into small groups - which helped to minimise disruption.
In a statement shortly after 1pm, gardaí said the protest had ended and that traffic was moving freely on the M50.
The protest involved up to 200 trucks. It was originally to have included 600 trucks, but the RTA agreed to a smaller number after talks with gardaí.
The RTA, 80 per cent of whose members were formerly with the Irish Road Haulage Association, is demanding that tolls on the M50 be lifted, a traffic-management structure for "continuous flow of traffic", and a regulator for the haulage industry.
The RTA said it was losing up to 40 per cent in business because of the changes for hauliers and lack of traffic management, and that it was "absolutely ludicrous" that truckers or ordinary motorists should have to pay tolls, given the delays.
Fine Gael transport spokeswoman Olivia Mitchell said it was "simply unacceptable" for the truckers to "use other beleaguered commuters as pawns to highlight their grievances.
"No matter how valid the case being highlighted by the hauliers, it is just unpardonable to ask commuters to tolerate further hours of delay to support their cause," she said in a statement.
AA Ireland says the hauliers have legitimate concerns, but "innocent commuting motorists do not deserve to be used as collateral damage", spokesman Conor Faughnan said.
