When two cars are driving parallel in the outside lanes of a three-lane motorway, who has priority to move to the middle first?
Few days ago I was presented in this exact situation; picture a 3 lanes motorway; empty; 110 speed limit; left lane 1 car, central lane empty, right lane 1 car.
I was in the overtaking lane (far right) and got this car tailgating me, wanting me to get the {profanity} out of my way. I did notice there's a car on the slow lane (far left) driving almost at the same speed as me (so we're talking about 110 km/h). I activated by blinker signalling left and waited because my gut feel is the car on the left lane about to go to the central lane .. so after a sec or two … nothing .. so i went to the central lane … AND yes as expected, the car on the left lane also went to the central lane. it almost happened … but luckily it didn't …
so what's the go here? who's at fault?
EDIT Update your post to say you were just overtaking a car in the middle lane. Otherwise, you will get blasted in 3.2.1..*
and the car from the left lane wanted to overtake a car in front of him by going to the central lane … i noticed this hence my hesitation; just a matter on timing so i waited and waited … then the moment i decided, the left lane car also decided .. so both of us went …
When I want to change into a lane and I can see another car looks like they may want to do the same thing - travelling at a similar speed and overtaking the vehicle in the lane between us, I will put on my indicators but wait an extra few seconds than normal to see if they'll put on their lights or make a manoeuvre. If they see I have my indicators on, they'll wait for me to merge, otherwise I just play it safe and let them do it first, and either merge in front or behind them afterwards.
Just play it safe and you should be good the vast majority of the time in these sorts of circumstances, and in the few scenarios you both still merge at the same time, keep your eyes open and be prepared to abort.
