The idiom "to have one for the road" means to have one last drink before leaving a place, especially before a long journey. It is often used when someone is about to leave a party or a bar and wants to have one last drink before heading out.
The phrase suggests that the person is taking one last opportunity to enjoy themselves before they leave, and it can also imply that they are not in a hurry to leave. However, it is important to note that this phrase should be used with caution, as it can also suggest that the person is not being responsible by drinking and then driving.
In general, it is best to avoid drinking and driving altogether, and to plan ahead for transportation if you know you will be drinking. If you do choose to have "one for the road," make sure you are not putting yourself or others in danger by driving under the influence.
