In this situation the No....
In this situation the No. 84 car definitely knows where the No. 55 car is. The spotter for the 55 should stay with his driver as he exits Turn 2 and tell him "outside...still outside...still there." If he doesn't clear the front of the 84, he could get turned around into the outside wall while the 84 motors on.
Before the season and/or before a particular race, do some pre-planning with the driver and crew chief about strategies and alternatives in the event certain things take place. For example, some teams choose to pit during an early caution in a longer race that requires a stop, so that when the rest of the field pits, they will be at the front for the final stint.
This only works well if you have gotten behind due to a spin or flat tire that put you to the rear and you need to get back up front. The drawback to this is that the late pitting teams will have fresher tires (if everyone puts on new rubber) and be faster.
Preplan for contingencies, such as what to do if a caution comes out and you need to make an adjustment. The spotter must, in most cases, eye the pit entrance to make sure pit road is open. He must also tell the crew what is happening with the car so they can be ready. And, he has to keep track of the pace cars location and relay that to the team so they don’t go a lap down.
A flat tire going into Turn 1 may not get noticed by the crew, so the spotter needs to relay the situation to the crew so they will be ready. The driver may say, “I’ve got a tire going down,” but not know which one. The spotter may be able to eye which tire so the crew can have the correct size and pressured tire for that corner ready.
On the restart, if the car behind is laying back and making a run at your first place position, tell the driver so he can make him lift and brake, “wait, wait, wait…,” then say, “go, go, go” once the car behind has committed to lifting. Oh, the possibilities!
Spot like you’re in the seat beside the driver, or better yet like you’re the driver. In my spotting for road racing, I have a great time. The Daytona Prototype cars run with the slower GT class and there is always overtaking occuring. At times you’re clearing your driver as quickly as possible so he can move over to setup for the next turn.
You’re letting him know that ahead is a very slow car. This is important because the closing rate may be too quick for the faster car to avoid a collision. This holds true for circle track racing too. If you’re side-by-side with someone racing for position, you need to know about a slow car on the inside so you can, a) crowd the other car to make him lift if you’re on the outside, or b) move the other car over enough to get by the slower car if you’re on the inside.
Know that you must “feel” when the driver needs to be cleared, just like if you were driving. Never clear too early, but don’t hesitate either. Know when a driver needs the information and what information he needs.
When your driver is passing a slower car on the outside down the straightaway, he needs to know exactly when he is clear so he can either take the normal line into the corner or stay up. It’s either one or the other, and if the information is delayed, he may lose valuable time if he could have taken the low line.
In this case, by all means, key the mic early and as soon as clear happens, say “clear.” If it happens to be a sudden announcement, I usually say two words, “you’re clear” so that if I cut off the first word, “clear” comes through.
Again, both cars see each...
Again, both cars see each other, but in this case, the blue car is the faster car passing on the inside and needs to be cleared as soon as he clears the No. 27 car off Turn 2 so he can naturally drift up to the wall. If he isn't clear by that point, then he also needs to know to avoid getting into the 27's front fender. This is common because although the blue car might be overall faster, he can't get a good exit off the turn and doesn't make it by the 27 in time to drift up. It may take several laps of this before he succeeds.
There are a few advanced techniques you can develop and use when spotting. When you get comfortable, you can begin to look well ahead and watch other cars at times when your car is all clear. And let the driver know every time he is all clear. That gives him a chance to relax his guard a little until he reaches new traffic in order to reduce fatigue.
Watch for future conflicts developing and if need be, alert the driver to them. If two cars get to racing side by side up ahead, they may be slowing down and this may be an opportunity to be alert to an opportunity to pass both cars if they were to get together and move up the track.
Be on the alert for caution situations, not necessarily waiting for the caution to come out. If an obvious caution situation develops, tell the driver immediately so he doesn’t get into it. The flagman may be looking in another direction, as often happens, and the actual caution may come out too late for your car to avoid a problem.
If a car blows a motor, tell the driver, “Stay high in 3 and 4, oil on the track” so he doesn’t go flying in there and then slide to the wall. This kind of knowledge is a bit advanced and only veteran spotters are good at it, but it will help your racing program a lot if you can develop a holistic approach to your spotting duties.
Good driver/spotter relationships often are a significant part of winning races and championships. The longer you work together, the better it gets. Talk to other veteran spotters and let them help you to get better. These guys are going to be beside you at every race and a sort of camaraderie can develop in many cases. Good luck and speak clearly.
