Border Crossings Serbia
 

Has anyone crossed from Greece ( Thessaloniki Direction) to Masedonia ( for Skopje), Masedonia to Serbia, and Serbia to Croatia at Novi Sad, recently. There are main border crossings on the principal roads, but there are also some other lesser crossings, but these would involve a little exta mileage, 30 in the ex Greece case.
Can find little info on the interrnet as to whether there could be long delays and would it be worth taking the lesser crossings. I have an ID Licence, Green Card , UK registered bike and UK Passport.
Finally is it acceptable withouty causing a riot, for a motor cycle to head to the top of the queue.
Am crossing early July 2019.
Any help much appreciated.
