Yes, and to help you'll have either a clutch brake that engages when clutch is completely depressed, or a countershaft brake that is engaged with an air button on the shifter.
Both of them stop the transmission from spinning when you're at a stop and ready to slip it in gear again and take off. Without one or the other it can take quite a long time to get it in gear if the oil is warm and it's spinning good.
