Drivers choosing a soft drink
A tonic on its own or a drink explicitly sold as non-alcoholic keeps spirits out of the driver’s serve. GOV.UK cautions that the drink-drive limit cannot be converted into a personal number of drinks.
Who is choosing?
Groups comparing sugar and sweeteners
If some travellers want tonic without sugar, compare the nutrition panel and ingredients rather than relying on words such as “light”. A sweetener may matter to someone sharing the drinks.
Shoppers who prefer botanical flavours
Quinine and botanical ingredients offer another flavour direction alongside savoury snacks. Check the chosen drink’s sugar information as well as its flavour description.
What matters when choosing?
Decide what the driver will drink before comparing flavour, nutrition and pack size; these answer different questions about the finished drink.
| Priority | What to check | Your needs |
|---|---|---|
| Alcohol in the serve | Check how the finished drink is described. If using a soft mixer, establish whether any spirit will be added. | If I’m driving, I want a drink explicitly sold as non-alcoholic or a soft mixer served without spirits. GOV.UK says no personal drink allowance can be calculated from the legal limit. |
| Sugar and sweeteners | Compare sugars and energy per 100 ml, then read the sweetener ingredients and warnings. Low calorie and no sugar do not describe alcohol content. | For a no-sugar tonic, I would check the exact pack label. Sainsbury’s lists its 1-litre Schweppes Slimline Tonic Water at 0 g sugars and 2 kcal per 100 ml, with aspartame and a phenylalanine warning. |
| Flavour | Look for the stated tonic, ginger or citrus ingredients and check the nutrition panel separately. Fentimans lists quinine and fermented botanical extracts in its Premium Indian Tonic Water. | With savoury snacks, I might prefer a bitter tonic to a ginger or citrus drink; the flavour choice does not settle the sugar question. |
| Pack format | Compare the number and size of cans or bottles with the number of people drinking and the space available to carry them. | For separate drinks during the journey, I may prefer small cans; a bottle makes more sense when we plan to share it at a stop. |
What should you avoid overlooking?
-
Treating “light” and “non-alcoholic” as interchangeable
Calorie and sugar descriptions tell you nothing about a spirit added to a mixer. They also answer a different question from the alcohol description of a finished drink.
For a driver, choose an explicitly non-alcoholic drink or serve the soft mixer without spirits. Read the nutrition panel separately if sugar or sweeteners matter.
-
Using the drink-drive limit as a target
GOV.UK says the limits differ in Scotland and the rest of the UK, and that it is impossible to say exactly how many drinks equal a limit for any individual.
If you will drive, do not work backwards from a legal limit to decide how much to drink; choose a non-alcoholic serve instead.

Choosing slimline tonic without reading the ingredients
Sainsbury’s lists aspartame and a source of phenylalanine in its 1-litre Schweppes Slimline Tonic Water. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU).
Check the ingredients and warnings on the exact pack, particularly if someone sharing it has PKU.

Common questions
Can I have a low-alcohol drink if I will be driving?
Do not use “low alcohol” or the legal drink-drive limit as a personal drinking allowance. GOV.UK says it is impossible to say exactly how many drinks equal the limit for an individual; choose an explicitly non-alcoholic drink or a soft mixer without added spirits.
Does low-calorie tonic mean the finished drink is alcohol-free?
No. Calories, sugar and alcohol describe different characteristics, and adding spirits changes a soft mixer’s finished serve. Check what you are actually drinking as well as the mixer’s nutrition label.
What should I check in sugar-free tonic?
Read the sweetener ingredients and warnings on the exact pack. Sainsbury’s lists aspartame and a source of phenylalanine in its 1-litre Schweppes Slimline Tonic Water; the NHS says aspartame is unsuitable for people with phenylketonuria (PKU).
Should I pack cans or a larger bottle?
Choose small cans if people want separate drinks during the journey; consider a larger bottle when the group plans to share it. Fever-Tree describes its cans as suited to use on the go and its bottles as suited to sharing, but check the size of the particular pack.
