A manoeuvre is any change of speed or position. There is a whole science as to the best way to accomplish any manoeuvre. Again, acronyms are offered up as help:
MSM= Mirrors – Signal – Manoeuvre.
The actual Manoeuvre part of the manoeuvre is then broken down into another sub-division acronym:
PSL : Move into Position in good time; Ensure your vehicle is traveling at the appropriate Speed and in a suitable gear to complete the manoeuvre safely. Look, (further comprised of another acronym, LADA: Looking (What can you see?) Assessing (What are your options?) Deciding (Depending on what you see) Acting (either continue or wait).
So, in a nutshell, before doing anything, be sure you MSM(PSL[LADA])
At this rate I think I would rather not take the turn or change speed 😉
haha! just give up and go home!!
