Do you feel lucky? That's pretty much what it comes down to. I guess you could look at it like if you get halfway there, you have a shorter, thus cheaper, tow.

Initial check. Take a voltmeter and check battery with car turned off.   Should be around 12.3 volts if decent charge. Then start the car if you can. Voltage across the battery should be 14.3+ Volts if charging.  If not, then either alternator is bad, voltage regulator is bad or loose wires to alternator like the ground. That's an initial test to see if the battery is getting charged. If less than 14 volts, then the car is running on the battery and it won't run very long.

With an older car, and if the battery is strong, I think it can make it. If it were a more modern car with electric everything, maybe not. It is a gamble though. I would risk it myself. 

Silly of me to ask, but ask I must: Does your car insurance policy cover a short tow? Or, do you have a AAA membership (which also covers a tow)? 

ride a bike, and put the alt in yourself. It's easy.

So the other day my 1995 Nissan Maxima with 168K miles died while driving and I believe it's the alternator. Here are the things that happened in order and these things never happen until the drive right before my car died. 1. Abs light came on. 2. Radio stopped working. 3. Clock turned dim then stopped working. 4. Speedometer stopped working and cluster light got dim. 5. The car shook like it's stalling then the car died. I think it's the alternator that went out right? I know I might need a new battery as well. Any help is appreciated. 

It really depends how good and charged your battery is. I was very very very very very lucky when my Chevy Cavalier alternator quit on the way home at new moon (dark) night. Lights got dim about 5 miles from home. Turned off everything, including lights, Hung my flashlight out my window so I could be seen. Got off the freeway by my house. No stop signs stops. Then car was doing weird things since needs computer to drive trans, etc. Flashlight out the window looking for critters in the road and to be seen. Crest a small hill. Rolled down and around thru the neighborhood and then was in neutral the last 600 feet downhill. Rolled into my driveway dead. No power steering. Made it. In the morning found my alternator ground wire broke, from vibration. Fixed it. All good. So yes, MAYBE you can make it. Depends how far. 

Easy initial test. With a voltmeter, check voltage of the battery. A decent charged battery should be 12.3 volts or better. Start the car, Check voltage across the battery, it should be around 14.5+ volts. If not, then know the battery is not getting charged. At that point either the alternator could be bad.    If your computer is the voltage regulator for the alternator(Dumb design) then it is not regulating charge to the battery. My old Jeep has the computer regulating the voltage. When  a ground went bad, the computer committed suicide and burned itself up. Stupid design for computer to regulate.  I suggest tow it or mobile mechanic if you cannot check yourself.  Good luck

Depends on how quickly your car will drain the battery getting to the shop, and how lucky you feel.
