When at traffic lights and local knowledge tells you it's going to be a long wait, is it sensible to turn your engine off? I'm talking about a non stop-start vehicle.
I've started doing this I recently but am not sure whether it's beneficial or advisable.
Your thoughts?

The gearshift lever is in Neutral.
The clutch pedal is not pressed!
The driver has fastened the seat belt.
The driver's door is closed.
The bonnet is closed.
The vehicle is at a standstill.
The factory-fitted towing device is not electrically connected to a trailer.
The engine has reached its operating temperature.
The charge state of the vehicle battery is sufficient.
The stationary vehicle is not on a steep slope or a steep downhill section.
The engine speed is less than 1200 RPM.
The temperature of the vehicle battery is not too low or too high.
The pressure in the brake system is sufficient.
The difference between the outdoor- and the set temperature in the interior is not too great.
The vehicle speed since the last time the engine was switched off was greater than 3 km/h. meaning if you're crawling forwards in start-stop traffic, then it won't switch off every time, as well as low speed manoeuvres in a car park.
No cleaning of the diesel particle filter takes place
The front wheels are not turned excessively (the steering angle is less than 3/4 of a steering wheel revolution).

My car has a separate battery for the stop-start function. It's in the boot, and a lot smaller than the normal battery, similar to a motorcycle battery.

The Intelligent Stop/Start system is able to restart smoothly in less time than it takes for the driver's foot to release the brake pedal and depress the accelerator. It does so by utilising a Twin Solenoid Starter (TSS) mechanism that features its own secondary battery to ensure that in-car systems requiring power are not affected.
