Yes you can identify it by colour, smell and taste.
Diesel for road vehicles is known as DERV (Fuel for Diesel Engined Road Vehicles) or ULSD (Ultra Low Sulphur Diesel which has a reduced sulphur content) and is white in colour.

Diesel fuel smells different to gasoline. A simple test is to pour a little of the fuel onto your fingers, and rub the fuel between thumb and finger. Diesel fuel will feel oily where gasoline is not oily. In some countries gasoline may have colour added, so if it's say red/pink it could be gasoline. But in other countries - such as the UK - farmers can buy cheap "agricultural" diesel that is a red colour only for use in tractors and other farm machinery. So you can't rely on the colour unless you know for sure which colours are standard in your country.
Take a sample out and check following; Colour - Petrol is almost clear, diesel is more yellowy Smell - Diesel and Petrol both have distinctively different smells, only way is if you get a sample of either as a reference Flash point - Petrol has a much lower flash point so will burn if ignited whereas diesel wont. If you take a very small sample and under safe and controlled circumstances try to ignite with a match if burns is petrol if not diesel Hope this helps
